Intracranial Hypertension Caused by an Ependymoma of the Lumbar Thecal Sac with Normal Cerebrospinal Fluid Composition

Abstract

Tumors in the spinal canal are a rare but well-known cause of intracranial hypertension. Possible pathophysiologic mechanisms include disruption of CSF absorption at the arachnoid granulations due to high protein or degradation products in the CSF or blockage of cerebrospinal fluid (CSF) outflow from tumors
