Hey, everyone! :)

My close friend, Walter, is 55 and has untreated congenital hydrocephalus. He will be having an ETV soon. A small AVM, about the size of a quarter, was found on his last CT. It's on the top of the brain, and nsg says she'll monitor it to see if surgery is necessary. He has headache and some seizures, despite several meds, but it's hard to know if they're due to the AVM or the hydro. He'll have an MRI soon, so we may know more then.

Has anyone been in a similar situation? What was your outcome? TIA for any info! <3
