Spontaneous Intracranial Hypotension Treated with Epidural Blood Patch: A Case Report

Abstract

Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous cerebrospinal fluid (CSF) leakage, resulting in orthostatic headache as the main symptom, but other symptoms such as memory loss, nausea, and tinnitus may also be present. Various imaging techniques are used to diagnose SIH, with magnetic resonance imaging myelography being an important tool for detecting the leakage site of CSF. Conservative treatments including hydration, bed rest, and intravenous caffeine have been tried with limited success. Epidural blood patch (EBP) is the most commonly performed treatment for SIH after the failure of conservative management. There are different opinions about the EBP procedure (e.g., blind EBP vs. targeted EBP). This report describes the treatment of SIH with targeted EBP according to imaging diagnosis after the failure of initial blind lumbar EBP.
