Most of these findings are the result of vascular dilation to compensate for sudden depletion of Csf volume, the explanations are based on Monro Kellie hypothesis, which states that the sum of the volumes of intracranial blood, CSF, and brain tissue remain constant in an intact cranium. Meningeal enhancement is thick, linear, without nodularity and involves the pachymeninges without evidence of involvement of the leptomeninges.
Dura matter, the innermost layer composed of fibroblasts with inter digitating processes that create spaces in between. Sub dural effusions occur when the extravasation continue even after meningeal thickening and enhancement, to the point of fluid accumulation in the subdural space as supported by studies in which effusions were not seen in the absence of meningeal enhancement represent more advanced stage of the condition. Subdural hematoma occur when effusion get complicated with bleed in subdural space due to rupture of the bridging veins traversing sub dural space in response to traction by ongoing extravasation and effusion.
Descend of cerebellar tonsils with sagging of brain stem, an associated effacement of prepontine cistern, obliteration supra chiasmatic cistern with inferior displacement of the optic chiasm result from reduction of normal Csf buoyancy due to reduced csf volume and represent most advanced stage of disease and severe Csf volume depletion, occurs after all other compensatory mechanisms have exhausted. Engorgement of dural venous sinuses seen as enlarged and round dural venous sinuses which are normally triangular in shape on cross sections. Regression in these imaging findings often parallels clinical improvement of these, reversal of pituitary enlargement occurs first. Most important is after sincerely mentioning all the findings, one must mention or suggest about the condition of so called intra cranial hypotension in the report, a frequently misdiagnosed syndrome of headache caused by reduced intra cranial pressure to alarm clinician that sagging down brain stem and tonsillar desend is due to low intra cranial pressure and not secondary to raised intra cranial pressure due to bilateral sub dural hematoma.

I have looked into some veterinary databases for you, and there is nothing reported connecting acute deafness with an MRI of the drugs you listed. But, I was surprised to learn myself that general anesthesia itself may cause deafness in both ears from unknown causes.
Here are the findings (it is pretty rare): “Sixty-two cases of hearing loss following anesthesia were reported between the years 2002 and 2009.

Apart from routine X-rays, CT scans, MRI, Angiogram, Ultrasound of Neck including Thyroid & Fine Needle Aspirations are carried out. Extravasation of fluid occur into this layer, in these spaces, in response to increased dural vasculature as the dura lacks blood brain barrier and tight junctions.These extravasations explains dural thickening as well as contrast extravasation and enhancement. In fact it is the most common nerve among all to get affected due to its longer intracranial course. In rare cases, animals awaken from anesthesia deaf in both ears, often following ear cleaning or teeth cleaning.
Stevens- Sparks Out of Louisiana State University found that, “Deafness can be a consequence following anesthesia for dental or ear cleaning procedures.
Laci Schaible is a US trained veterinarian with over 15 years experience in small animal medicine and surgery. Dilation of the venous side of circulation contributes a lot due to its high compliance and capacitance.
Tight junctions in arachnoid and pia mater prevent the similar contrast accumulation, explaining enhancement is limited to the dura.


Often get encountered at inisura when there is sagging of mid brain with antero posterior elongation. She was given the following drugs during the MRI: Diazepam, Glycopyrrolate, Hydromorphone, Isoflurane, Naloxone, Propofol. It may be the case that the body shunts blood away from the cochlea (a part of the ear) during anesthesia to protect other critical organs, or that pressure or jaw positioning compresses the arterial supply to the cochlea. Though it is a frequent finding, abnormal meningeal enhancement is not the rule as cases are reported which are still symptomatic but enhancement that resolved earlier where as in certain typical cases MR images never revealed enhancement at any stage of disease.
A similar outcome is noted in humans with a condition called ischemia of the vertebrobasilar artery.
The inner ear is especially vulnerable to reduced blood flow because it has no backup circulation and the tissues have very high energy metabolism. No relationship was observed between deafness and dog or cat breed, gender, anesthetic drug used, or dog size. But even more than the number of times your dogs has vomited, so is the long list of causes of vomiting in dogs.
This reinforces the need for a good otic examination to rule out ear canal obstruction or middle ear infections.
