So I got an MRI from my ENT to rule things out.  He called and told me everything looked normal.  I got mychart report about it and it said below:

1. Normal appearance of the internal auditory canals, cerebellopontine

angles and inner ear structures with no evidence for vestibular

schwannoma.

2. No evidence of acute intracranial hemorrhage, infarction or

intra-axial mass. Incidental posterior fossa arachnoid cyst is present.

My question is about the "Incidental posterior fossa arachnoid cyst is present". Does Is that good or bad? ENT said everything was normal.  Hoping someone else has some more information.  Thanks!

    Also said this: 1.4 x 2.4 x 2.5 cm arachnoid cysts posterior to the cerebellar vermis.

    It was discovered that I had an arachnoid cyst after having an mri brain scan. I went for a follow up appointment at ent and had two consultants waiting to tell me about it. They said it was nothing to worry about unless you start to get symptoms. Since then whenever I’ve asked my doctor or consultant about it I’ve more or less been told to stop fussing about it, you can hardly see it on the mri. I just wonder why I was told about it at all!

      It seems like the symptoms of the can mimic MD so couldn't it be causing the MD?

      I don’t know, it’s about 8 years ago and at that point I was having problems hearing, but no md.  What does it mean, with contrast?

      This is for Michael too. 

      Did you have a contrast dye injected before your MRI?

    I found this on PUBMED.gov.

    "Abstract

    Arachnoid cysts of the posterior fossa are rare. When arachnoid cysts are encountered, the presenting symptoms are frequently otologic, with hearing loss and imbalance occurring commonly. Three cases are presented with a previously unreported otologic symptom, that of bilateral hearing loss, which in one case was fluctuant. None of the patients had the common symptoms of unilateral hearing loss and headache. With the advent of computed tomography and magnetic resonance imaging, these cysts may be readily identified, usually with diagnostic imaging alone. Unfortunately there is often a delay in diagnosis because of the vague and fleeting nature of the symptoms. Because no single diagnostic symptom pattern is able to characterize all cases, it is believed computed tomography or magnetic resonance imaging or both are indicated in patients with long-standing otologic complaints--even in the absence of unilateral symptoms. Treatment of posterior fossa arachnoid cysts primarily consists of surgical procedures designed to decompress the cyst. In this series, treatment with diuretics alone resulted in improvement of symptoms during several years of followup, with no evidence of enlargement of the cysts."

    Suggest you ask some more questions of your ENT consultant.
