Cerebral Venous Thrombosis Caused by Spontaneous Intracranial Hypotension: A Case Report

This case report presents a rare case of cerebral venous thrombosis (CVT) caused by spontaneous intracranial hypotension (SIH). The cause and prognosis of CVT can vary; CVT caused by SIH is uncommon and difficult to diagnose and treat. In this case, magnetic resonance imaging myelography showed definite cerebrospinal fluid leakage, and the patient's symptoms did not improve after conventional treatment. Furthermore, subdural hematoma occurred, causing mental deterioration; however, it improved dramatically after the blood patch procedure and burr hole drainage, which was performed after early cessation of anticoagulant therapy.
