Cerebral Venous Thrombosis as a Complication of Spontaneous Intracranial Hypotension: A Case Report

Abstract

Spontaneous intracranial hypotension (SIH) is an uncommon condition caused by cerebrospinal fluid (CSF) leakage, which can lead to complications such as cerebral venous thrombosis (CVT), occurring in 1–2% of SIH patients. This case report describes the presentation, diagnosis, and management of SIH complicated by CVT. A 36-year-old woman with no comorbidities presented with a three-week history of severe, initially orthostatic headaches. Neurological examination revealed mild bilateral disc oedema, and imaging showed generalized brain oedema. MRI with MRV confirmed cerebral venous sinus thrombosis along with typical SIH features, including pachymeningeal enhancement and venous engorgement. She was treated with heparin infusion and
isotonic saline, responding well without seizures or hemorrhagic complications. This case highlights the risk of CVT in SIH and underscores the importance of early diagnosis through neuroimaging and lumbar puncture. The patient’s favorable response to anticoagulation demonstrates effective management, though further
studies are needed to establish definitive treatment guidelines for SIH-associated CVT.
