Abstract

Idiopathic Intracranial Hypertension is a condition characterised by raised cerebrospinal fluid pressure of unknown etiology seen predominantly in obese, middle aged patients. The typical clinical features include headache, pulsatile tinnitus, diplopia and transient visual obscurations. Seizures are a rare symptom seen in IIH patients. We present a case of a young, obese female patient who presented with headache and seizures. Imaging showed evidence of Idiopathic Intracranial Hypertension with temporal lobe encephalocoeles and brain herniation into arachnoid granulations. The diagnosis was subsequently confirmed by clinical workup and she was started on treatment for the same.
