Since many of these symptoms may overlap with other nasal and sinus conditions, the timing, specific combination of symptoms, and other tests can often help to find the correct diagnosis for your problem. If your symptoms do not improve as you reach 10 to 14 days, you may be suffering from acute bacterial sinusitis. The scope used for a nasal endoscopy is a lighted tube that allows the structures in the nose and sinuses to be seen more easily than by simply looking into the front of the nostrils.
X-Rays: X-rays were used in the past to image the sinuses, but plain X-rays are no longer routinely performed to help in diagnosing sinusitis. CT scan: Usually, radiologic studies are not performed for the initial diagnosis or treatment of sinus infections. Viral Upper Respiratory Infection (URI) or Common Cold: While many of the symptoms of a viral cold are the same as bacterial sinusitis, these conditions are treated differently. Environmental Allergies: The symptoms of environmental allergies and sinusitis overlap to some degree. Acid Reflux: Acid reflux (stomach acid coming up to irritate the esophagus or throat) may contribute to a number of symptoms that are commonly associated with sinusitis.
We have discussed the most common symptoms, time course, and diagnostic tests for sinusitis.

To provide even greater transparency and choice, we are working on a number of other cookie-related enhancements. October 21, 2010Cerebral venous thrombosis is an important cause of stroke especially in children and young adults. It is a difficult diagnosis because of its nonspecific clinical presentation and subtle imaging findings. Vein of Trolard, which is the largest cortical vein that drains into the superior sagittal sinus. Clinically patients with cerebral venous thrombosis present with variable symptoms ranging from headache to seizure and coma in severe cases. Venous thrombosis has a nonspecific presentation and therefore it is important to recognize subtle imaging findings and indirect signs that may indicate the presence of thrombosis.
Although these findings are often present on initial scans, they are frequently detected only in retrospect.
Clinically patients with venous thrombosis often present with seizures, which is not a symptom in patients with an arterial infarction.
Direct visualization of a clot in the cerebral veins on a non enhanced CT scan is known as the dense clot sign. Normally veins are slightly denser than brain tissue and in some cases it is difficult to say whether the vein is normal or too dense (see pitfalls). Visualization of a thrombosed cortical vein that is seen as a linear or cord-like density, is also known as the cord sign.
On the left images of a patient with a hemorrhagic infarction in the temporal lobe (red arrow). The empty delta sign is a finding that is seen on a contrast enhanced CT (CECT) and was first described in thrombosis of the superior sagittal sinus. The sign consists of a triangular area of enhancement with a relatively low-attenuating center, which is the thrombosed sinus. The likely explanation is enhancement of the rich dural venous collateral circulation surrounding the thrombosed sinus, producing the central region of low attenuation. In early thrombosis the empty delta sign may be absent and you will have to rely on non-visualization of the thrombosed vein on the CECT. On the left a case of thrombosis of the right transverse sinus and the left transverse and sigmoid sinus (arrows).
On spin-echo images patent cerebral veins usually will demonstrate low signal intensity due to flow void. Flow voids are best seen on T2-weighted and FLAIR images, but can sometimes also be seen on T1-weighted images.
Although this is not a completely reliable sign, it is often one of the first things, that make you think of the possibility of venous thrombosis. On the left a T2-weighted image with normal flow void in the right sigmoid sinus and jugular vein (blue arrow). Absence of normal flow void on MR (2)The images on the left show abnormal high signal on the T1-weighted images due to thrombosis. The thrombosis extends from the deep cerebral veins and straight sinus to the transverse and sigmoid sinus on the right. Absence of normal flow void on MR-images can be very helpful in detecting venous thrombosis, but there are some pitfalls as we will discuss later.
The other sign that can help you in making the diagnosis of unsuspected venous thrombosis is venous infarction.
Venous thrombosis leads to a high venous pressure which first results in vasogenic edema in the white matter of the affected area.
When the proces continues it may lead to infarction and development of cytotoxic edema next to the vasogenic edema.
This is unlike in an arterial infarction in which there is only cytotoxic edema and no vasogenic edema.
Due to the high venous pressure hemorrhage is seen more frequently in venous infarction compared to arterial infarction.
Since we are not that familiar with venous infarctions, we often think of them as infarctions in an atypical location or in a non-arterial distribution.
This is seen in thrombosis of the superior sagittal sinus, straight sinus and the internal cerebral veins. On the left bilateral parasagittal edema and subte hemorrhage in a patient with thrombosis of the superior sagittal sinus. On the left reconstructed sagittal CT-images in a patient with bilateral parasagittal hemorrhage due to thrombosis of the superior sagittal sinus. The red arrow on the contrast enhanced image indicates the filling defect caused by the thrombus.
On the left images demonstrating hypodensity in the white matter and less pronounced in the gray matter of the left temporal lobe.
There is a broad differential diagnosis including arterial infarction, infection, tumor etc.
In the differential diagnosis we also should include a venous infarct in the territory of the vein of Labbe.
The subtle density in the area of the left transverse sinus (arrow) is the key to the diagnosis.
This is a direct sign of thrombosis and the next step is a CECT, which confirmed the diagnosis (not shown). When the hemorrhagic component of the infarction is large, it may look like any other intracerebral hematoma with surrounding vasogenic edema.
The clue to the diagnosis in this case is seen on the contrast enhanced image, which nicely demonstrates the filling defect in the sigmoid sinus (blue arrow).
There is a combination of vasogenic edema (red arrow), cytotoxic edema and hemorrhage (blue arrow). These findings and the location in the temporal lobe, should make you think of venous infarction due to thrombosis of the vein of Labbe.
When you look closely and you may have to enlarge the image to appreciate this, there is also high signal in the basal ganglia on the right. A sagittal CT reconstruction demonstrates a filling defect in the straight sinus and the vein of Galen (arrows). On the left a young patient with bilateral abnormalities in the region of the basal ganglia. Based on the imaging findings there is a broad differential including small vessel disease, demyelinisation, intoxication and metabolic disorders.
Notice the abnormal high signal in the internal cerebral veins and straight sinus on the T1-weighted images, where there should be a low signal due to flow void. The diagnosis is bilateral infarctions in the basal ganglia due to deep cerebral venous thrombosis. In retrospect a dense vessel sign was seen in one of the cortical veins and the diagnosis of venous thrombosis was made.
The high signal intensity can be attributed to vasogenic edema due to the high venous pressure that resulted from the thrombosis. In the early stage there is non-enhancement of the thrombosed vein and in a later stage there is non-enhancement of the thrombus with surrounding enhancement known as empty delta sign, as discussed before. To be on the safe side we advocate 45-50 seconds delay after the start of contrast injection.


On the non-enhanced images you can appreciate the dense thrombus within the transverse sinus and the hemorrhage in the infarcted area. Transverse MIP image of a Phase-Contrast angiography.The right transverse sinus and jugular vein have no signal due to thrombosis. Time-of-Flight angiography is based on the phenomenon of flow-related enhancement of spins entering into an imaging slice. As a result of being unsaturated, these spins give more signal that surrounding saturated spins. Phase-contrast angiography uses the principle that spins in blood that is moving in the same direction as a magnetic field gradient develop a phase shift that is proportional to the velocity of the spins. Contrast-enhanced MR venography has the disadvantage that you need to give contrast, but has less pitfalls. On the left images of a patient with venous thrombosis, who was unconsious and did not respond to anticoagulant therapy. There is thrombosis of the superior sagittal sinus (red arrow), straight sinus (blue arrow) and transverse and sigmoid sinus (yellow arrow). Normally veins are slightly denser than brain tissue and in some cases it is difficult to say whether it is normal or too dense.
On the left an image of a thrombosed transverse sinus and next to it a normal transverse sinus. This results in a relative high density of the blood in the sagittal sinus compared to the brain, which simulates a dense clot sign. Because it is located in the area of the transverse sinus it simulates a thrombosed transverse sinus. Here a patient with a subdural hematoma on the left side, that has spread to the region of the superior sagittal sinus (arrows). By scrolling through the data set, it was obvious that it was an extention of the hematoma.
On the left three images of a patient with venous thrombosis in the superior sagittal sinus. There is arterial enhancement and it looks as if the superior sagittal sinus enhances, but in fact what we see is the shine through of the dense thrombus. Only on the image on the right, which was made 45 seconds after contrast injection there is an empty delta sign, which proves the presence of a thrombus in the sinus.
It can easily be mistaken for sinus thrombosis, because on the MRA one of the transverse sinuses is missing.
When you suspect, that there is a hypoplastic transverse sinus, then you should look at the size of the jugular foramen.
To differentiate whether there is a hypoplastic transverse sinus or thrombosed sinus, you need to look at the source images. On the left another case that demonstrates that you cannot fully rely on phase contrast imaging. The signal in the vein depends on the velocity of the flowing blood and the velocity encoding by the technician. On the contrast enhanced T1-weighted image it is obvious that the sinus fills with contrast and is patent.
Thrombus in right transverse sinus is dark on T2 due to intracellular deoxyhemoglobin (Courtesy dr. Normally when there is low signal in a vein, it is attributed to flow void and a sign of patency of the vein.
However at some stage of the thrombus there is intracellular deoxyhemoglobin, which is dark on T2 and mimics flow void.
On the left there is a thrombosed right transverse sinus with a delta sign on the contrast enhanced image. The sinus has a low signal intensity on the T2-weighted image as a result of the intracellular deoxyhemoglobin.
On the contrast enhanced T1-weighted image it is obvious that the sinus is filled with thrombus.
On the contrast enhanced T1 images on the left there is an area of low signal intensity within the enhancing transverse sinus. We can conclude that MRI has many false positives and negatives in the diagnosis of venous thrombosis. Chronic dural sinus thrombosis can lead to dural arteriovenous fistula formation and to increased CSF pressure. A DAVF or dural arteriovenous fistula is an abnormal connection between dural arteries, which are branches of the external carotid with the venous sinuses.
Sinus thrombosis is seen in many patients with a dural arteriovenous fistula, but the pathogenesis is still unclear (10). There are two possible mechanisms: (a) thrombophlebitis of the dural sinus may induce a dural fistula and (b) in the course of a dural fistula flow reversal may lead to thrombosis. Current classifications of DAVF focus mainly on the presence of leptomeningeal reflux related to cerebral venous hypertension leading to cerebral venous infarction or hemorrhage.
Notice the direct communication between the branches of the external carotid artery and the transverse sinus (blue arrow). In january 2009 there are signs of intracranial hypertension like CSF surrounding the optic nerve and CSF within the stalk of the hypophysis. In some patients dural sinus thrombosis may, even after recanalisation, lead to persisting disturbances in venous circulation. Clinically, these patients complain of headaches and they may have vision disturbances due to papil edema.

Former Miss USA, who now is training to compete in the MMA, was adventurous to say the least. In longstanding cases of sinusitis, also known as chronic sinusitis, non-infectious conditions are often the cause. Sinusitis may be classified in several ways, based on its duration (acute, subacute, or chronic) and the type of inflammation (either infectious or noninfectious).

The pain was no longer apparent on only hard surfaces, but during long drives and sitting at work for a long periods of time. This was done under the new stress that possible infection existed, waiting weeks to get the procedure done with pain getting worse exponentially. The term rhinosinusitis is also used to imply that both the nose and sinuses are involved.Acute sinus infection (also termed acute sinusitis caused by infection or acute bacterial rhinosinusitis) is usually defined as being of less than 30 days duration.

The decision was easy after many months trying to determine whether there was the possibility of infection.


The pain specialist examined the area around the tailbone and was not exactly sure what was causing the pain.
I wanted someone familiar with tailbone issues, typically a spine specialist and had no concern to removing the coccyx. Seeing the fracture and concluding a non-union was the only way to get to the right conclusion and 3 radiologist had missed this. It has been 10 weeks now and the pain is about the same level as when I went to my 1st visit to the pain doctor.
And she talks about her experiences competing in pageants, to transitioning into a world of fighting, and the insane mindset behind it all. You may have a common complaint that sends many people to their GP’s surgery: sinus trouble.
Never ignore professional medical advice in seeking treatment because of something you have read on the BootsWebMD Site. I believe my story is unique in that there was nothing for the basis of the cause of the pain and resulting debate over the MRI reports. Given this infection concern, I wanted someone who has removed tailbones, who is older with said experience, and who would know what to look for if the decision was to cut. So he reread the report and decided that the radiologist was 'hedging his bets' by stating possible infection; however, he would not recommend putting a needle anywhere, especially between the colon & coccyx.
With regards to the sinus tract, I could not conclude that fluid travels up as it would have to do in my body as identified in the MRI report. He is a Clinical Professor (retired) in the Division of Emergency Medicine, UT Health Science Center at San Antonio, and has been the Chief of Emergency Medicine at UT Medical Branch and at UTHSCSA with over 250 publications.
Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. Sinuses: Air spaces in your headSinuses are air spaces in your skull lined with mucous membranes.
I conclude that this became a battle of the radiologists and highly recommend that you locate the one with the most experience; probably one from a large (orthopedic) hospital with as much experience and focus. Here is where the story gets very interesting and a lesson on how to interpret MRI images & doctors. And although I spent additional time and resources ruling out infection, it was worth it as it lead to the real cause of my pain. At the time, I noticed that the pain was more noticeable, but only when I sat down on a hard surface. No evidence of fistulous connection (prefect asshole still!) They concluded that the coccygeal fracture fragments remained separated with sclerosis across the fracture plane consistent with nonunion. Everything looked good and he said that there was excessive movement (missed in colonoscopy exam). The report indicated a 'sinus tract' between the rectum and anterior (inside) of the tailbone and also anterior of the sacrum showing possible infection.
What is sinusitis?Tiny, hair-like structures called cilia (shown magnified here) help move mucus across sinus membranes and towards an exit. I had done some research (thank you internet) and concluded that it was probably due to ligaments. A cortisone shot would have been the solution if I had not pursued other options, but try to avoid this until you are most certain of the cause.
This was based on the problem I had with my feet (plantar fasciitis) in which the doctor described that ligaments later in life are like 'old rubber bands'.
Cortisone will allow for healing if you hit the right spot and treat the area with great care over a long period of 'healing' time.
Subacute and chronic forms of sinus infection usually are the result of incomplete treatment of an acute sinus infection. Given this fluid was on the anterior side (between the colon and coccyx, nobody wanted to take a biopsy; no needles.
Finally, if more serious complications of a sinus infection are suspected, such as spread to the orbits (eye sockets) or brain, a CT scan may be obtained for diagnosis.
Noninfectious sinusitis is caused by irritants and allergic conditions and follows the same general time line for acute, subacute and chronic as infectious sinusitis. Knowing that I had a non-union fracture besides any ligament issue, having a cortisone injection made no sense and the pain might come back.
Just a cold … at firstSinusitis usually starts with inflammation that’s triggered by a cold, allergy attack or an irritant, but it may not end there. The orthopedic doctor told me that if it was his ass, he would go to MD Anderson (Houston).
Find an experienced doctor who has performed many coccygectomy and feels comfortable performing the surgery.
As with my foot, a cortisone shot can reduce the inflammation and allow the ligaments to heal. Something wrong with the bone or ligament was my initial thought at the time and I communicated this to the pain doctor. They have seen just about everything and less risky if a biopsy was required to pull the fluid.
Although I have total faith in MD Anderson doctors, I went back to the 1st orthopedic doctor based on my criteria (above). There are side effects and I decided with stretching and inserts for my feet which was the right decision! This scare of infection had family telling me that I could die if the infection enters the spinal cord.
Most people have a stuffy nose and pain or pressure in several locations including the forehead, upper jaw, teeth, cheeks or around the eyes.
Chronic sinusitisThe blue areas in this colour-enhanced MRI show thickened mucosal surfaces of both maxillary sinuses. Inflammation of the sinus cavity that lasts for more than three months is chronic sinusitis. Although bacteria often colonise blocked sinuses, bacterial infections are not the only cause of chronic sinusitis. Anatomy, allergies, polyps, immune deficiencies and dental diseases may also cause chronic sinus problems. The swelling can be significant enough to cause grape-like masses called polyps (shown here). Polyps may protrude from the sinus into the nasal passage and partially or completely block the nasal airway. Nasal decongestantsDecongestants shrink swollen nasal tissue and help relieve nasal congestion, but always check with your pharmacist or doctor that they are suitable for you, and particularly before giving them to a child. They're available as a nasal spray or tablets, and are often found in combination cough and cold remedies. Usually, cold-related sinusitis tends to go away in around two to three weeks.Shown here is a magnified, colour-enhanced image of a rhinovirus pathogen responsible for the common cold. Treating allergy-related sinusitisRinsing the nose with a salt-water solution has been a traditional remedy for allergies or colds for many years.
Webmds sinuses on indications, contra-indications, benefits, and t-weighted images were first. When to seek medical adviceIf you keep feeling worse and symptoms are severe, or if you develop a high temperature, or symptoms last more than a week, it's time to seek medical advice.
If your sinusitis is very bad or keeps coming back, your GP may refer you to a specialist for an X-ray or CT scan. A first step is controlling pre-disposing factors, for example, eliminating environmental irritants, such as exposure to cigarette smoke. If lifestyle measures and medicines are not working to reduce sinus swelling and open the sinus passages, an operation may be necessary. Functional endoscopic sinus surgery (FESS) may also be used if there is a structural abnormality such as nasal polyps. A procedure called "turbinectomy" can also be performed to permanently shrink swollen nasal membranes.
Sinusitis complications: Worst-case scenariosIn very rare cases (about one in 10,000), infection can spread to the area surrounding the eye, the bones, the blood or the brain. If a sinus infection passes through the bone, it can infect the lining of the brain causing meningitis -- or even infect the brain itself.
If a sinus infection spreads into the orbit of the eye, it can cause an infection around the eye and possible blindness.
