My son became sick about six years ago. His first symptoms were stomach aches and then the headaches and blurred vision started. They first started working him up for Crohn's because I have it, but could never find it. Then they discovered he has pseudotumor cerebri, or the newer name is idiopathic intracranial hypertension. Now, they have decided he does have Crohn's also because of his ongoing problems with his peri-rectal fisutula. I have always thought the two are connected because they started at the same time. Has anyone else here ever had pseudotumor cerebri? It is basically too much spinal fluid in the skull and causes the symptoms of a brain tumor, although there is not actually a tumor. No doctor can really come up with a connection for us, although some have said it could be possible, they just don't know how.
