Decisions on Surgical intervention, Radiosurgery, Radiation Therapy and the use of chemotherapy are generally best made by a team approach, including input from the involved Neurosurgeon, Radiation Oncologist, and Medical Oncologist or Neurologist.
A slow growing almost always benign tumor that arises from the cells that cover the vestibular cochlear nerve. This type of tumor arises from star-shaped glial cells called astrocytes and most often occur in the cerebrum. Congenital lesions composed of a complex tangle of arteries and veins connected by one or more fistulae.
Craniopharyngiomas are tumors of abnormal tissue growth with benign histology and malignant behavior. These lesions have a tendency to invade surrounding structures and to recur after a seemingly total resection.
This tumor forms from cells lining the ependymal lining of ventricular system of the brain and spinal cord. While this tumor can be seen in adults it is often in diagnosed in children and teenagers and is the most common malignant brain tumor in childhood.
A tumor arises in the meninges, which are three thin layers of tissue surrounding the brain and spinal cord. This is a rare, slow-growing tumor that occurs in the cells that make up the fatty substance that covers and protects nerve cells in the brain and spinal cord. These tumors are rare, most often benign tumors most commonly affecting the base of skull and neck region. Information: Paragangliomas of the ear are benign, slow-growing vascular lesions that arise from a glomus body in the temporal bone or jugular bulb. Brown’s sign is evident during pneumo-otoscopy demonstrating blanching of the mass with the application of positive pressure.

These tumors grow slowly and , in some cases, it is warranted to watch the tumor and see if it is growing. In most cases, the special radiation treatment known as stereotactic radiotherapy will stop tumor growth.
This involves making an incision in the crease behind the ear and going through the ear bone directly to the tumor.
Most of the approach is through the ear, and there is very little manipulation of the brain in removal of a tumor in this fashion.

This tumor presents with hearing loss, balance problems, or ringing in the ears (tinnitus). Astrocytoma tumors do not usually spread outside the brain or spinal cord and usually will not affect other organs. They most commonly occur in young adults, with morbidity and death occurring in 30-50% and 10-15% of patients, respectively.

Craniopharyngiomas most frequently arise in the pituitary stalk and project into the hypothalamus.
Disease can often times involve the spinal cord, therefore treatment is often directed to the brain and spinal cord. This type of tumor is usually benign, but can be malignant, and generally is a slow growing tumor.
The pituitary is located in the sella turcica which is near the optic nerve and optic chiasm. Formerly known as glomus tumors, these are the most common benign tumors to arise in the temporal bone.
This is an 82 year old female with left sided pulsatile tinnitus of one year’s duration.
These tumors originate from the capillary bed of the epineurium surrounding the nerve and can either compress or infiltrate the nerve.
The hearing part, called the cochlear nerve, travels from the brain through the internal ear canal into the cochlea, or hearing portion of the inner ear. If the tumor gets very large, it will grow into the brain and eventually cause some imbalance and headaches with blurred vision.
The first goal is to ensure total removal of the tumor with no damage to the surrounding brain. This approach involves going through the bone above the ear and gently lifting the temporal lobe of the brain and drilling the bone over the internal ear canal.
Astrocytomas are the most common glioma and are often have clearly defined outlines on diagnostic images. They can become very large before symptoms occur, which often begin abruptly with seizures. Meningiomas can happen at any age, even to children, but most frequently arise in older women. Oligodendroglioma can occur in adults and children, and the average age of diagnosis is 35. Note the  erythema and pulsation of the glomus tympanicum tumor, which fills the middle ear space. Depending on location and the nerve of origin, these lesions can cause severe and progressive sensorineural hearing loss, tinnitus, facial nerve palsy, or vertigo even when they are relatively small. If the tumor is allow to grow to a giant size, it eventually causes death due to pressure on the brain. Large tumors are those that extend from the internal auditory canal through the spinal fluid and into the brain.
The presence of a small contrast-enhancing tumor in the internal auditory canal accompanied by severe sensorineural hearing loss and facial nerve palsy, should raise the suspicion of a hemangioma.

Fortunately, this rarely happens in the present day due to our methods to detect these tumors earlier. If the patient has symptoms or the tumor is in a critical area treatment is usually recommended. In many instances these tumors may not require treatment and in some instances can be treated with medication. They frequently invade the base of the skull and temporal bone and often present as a lesion in the hypotympanum.
Early recognition and surgical intervention in these benign tumors may improve the chance of preserving the functional integrity of the facial nerve and provides better results after nerve reconstruction.
It is impossible to differentiate a glomus tympanicum from a glomus juglulare invading the hypotympanum without radiographic imaging.
Due to their relative small size, the temporal bone CT-scan may show no evidence of pathological widening of the internal auditory canal or the typical intralesional calcifications at the time of presentation.
They are believed to occur more frequently in patients who swim in cold water and have been reported to be common in surfers.
MRI with Gadolinium is the imaging method of choice and a high index of clinical suspicion is necessary for the diagnosis of these tumors. Although the tumor is not likely to be cancerous, it is important to remove it in most patients because of the physical problems it can cause.
In this paper we report about a 51-year-old male presented with right-sided sensory-neural deafness and facial nerve palsy, accompanied by severe tinnitus and ipsilateral loss of vestibular function due to a cavernous hemangioma in the internal auditory canal.
Glomus cells are specialized cells that are found in some blood vessels, as well as along nerves. They act to detect changes in the bloodstream, such as the presence of a certain chemical or a change in temperature. The jugular foramen region of the temporal bone in the skull contains many nerve bundles with glomus cells. These are thought to be acquired mutations that cause the tumors, rather than hereditary genes. This means that mutations causing the tumors are acquired during a persons lifetime and are not passed on from one generation to the next. The symptoms, as well as an examination of the ear and throat area, can indicate that a tumor may be present. Either test can give a doctor a detailed image of the area in question and confirm or deny the presence of a tumor.
If it is not removed, it will continue to grow slowly and cause more problems as it gets bigger.
