Pseudotumor Cerebri Associated With Idiopathic Cryofibrinogenemia

Abstract
THE usual criteria for the diagnosis of pseudotumor cerebri are increased intracranial pressure, nonfocal neurologic signs, normal cerebrospinal fluid (CSF), and a normal ventricular system.1,2The syndrome has been seen in various metabolic disorders and following thrombosis of one or more dural sinuses. We are reporting what we believe to be the first case of idiopathic cryofibrinogenemia associated with multiple dural sinus thromboses that led to the development of pseudotumor cerebri. Report of a Case Clinical Course.— A 23-year-old man was well until December 1967, when he developed pyelonephritis and was treated with oxytetracycline.
