Tramur, brain cysts and noes bleeds

Hello,
My partner is 35 years old and around 3 years ago he had a moto bike accident where they did a CT scan and found an Aracnoid cyst. From the accident he had sever concussion for months, it took a year to get his concept of time back and his short term memory and eye sight has never been the same.  Over the bast 8 months his eye sight and hearing has significantly gotten worse. We have been seeing a neurologist and been getting tests done to see what is going on. The cysts stretches form the base of his brain and stretches up and over to the top of the left side of the brain, it is pushing his brain 4mm off center and remolding his scull. Today he has started getting noes bleeds, is this a possible cyst related problem? He is not one for noes bleeds.

Hi!
Yes, it is possible that there was an enlargement in the cyst size post head trauma during the bike accident. It may not have become evident on the first CT. Hence, it is important to get a MRI done or a repeat CT as the neurologist advises. The progressive loss of hearing and vision can also be due to benign intracranial hypertension (raised CSF pressure). Please consult your neurologist regarding this possibility. Take care!
