Fever as a Clinical Presentation of Acute Hydrocephalus: Two Case Reports and a Review of Literature.

Fever is often associated with infectious, traumatic, or allergenic etiologies, a known consequence of the systemic inflammatory response. Its association with a rise in intracranial pressures (ICP) is an uncommon presentation. We herein describe two patients who developed acute hydrocephalus and presented with high-grade fever. This febrile component was resistant to conventional antipyretics and was only relieved by cerebrospinal fluid (CSF) diversion.
