A Case of Spontaneous Intracranial Hypotension Complicated by Isolated Cortical Vein Thrombosis and Cerebral Venous Infarction

Intracranial hypotension is a syndrome of low cerebrospinal fluid (CSF) pressure characterized by postural headache (1). It may occur following lumbar puncture, craniotomy, spinal surgery, or spontaneously – so-called spontaneous intracranial hypotension (SIH). The diagnosis of SIH can be challenging. Recent reports have emphasized intracranial magnetic resonance (MR) findings in SIH (1–4). However, SIH complicated by cerebral sinus venous thrombosis has been mentioned rarely in the literature (5, 6). We present a rare case of SIH complicated by isolated cortical vein thrombosis (ICVT) and cerebral venous infarction. Therapy with epidural blood patch and intravenous heparin was successful.
