Abstract

Cerebrospinal fluid-venous fistula (CSFVF) is an increasingly recognized cause of spontaneous intracranial hypotension (SIH). We present a rare case of a 41-year-old woman with SIH caused by a right S2-S3 CSFVF draining in the right internal iliac vein. Successfully transvenous endovascular embolization using Onyx was performed. This report highlights diagnostic challenges and procedural details, emphasizing the efficacy of endovascular approaches in managing CSFVF in atypical anatomical locations.
