Cerebrospinal Fluid Rhinorrhea Secondary to Idiopathic Intracranial Hypertension

Abstract

Idiopathic intracranial hypertension (IIH) is a syndrome of increased intracranial pressure without a mass lesion or ventriculomegaly and normal cerebrospinal fluid (CSF) composition. Patients typically present with a headache and visual symptoms and signs. Here, we discuss a rare presentation of spontaneous CSF leak secondary to IIH and mild ophthalmic finding that worsened after the cranial repair of the CSF leak.
