Spontaneous intracranial hypotension complicated with cerebral venous thrombosis and subdural effusion: a case report

Spontaneous intracranial hypotension treatment can be complicated by concomitant cerebral venous thrombosis and subdural hematoma. A 48 years old male, presenting orthostatic headache and neck pain for 1 month displayed sagittal sinus thrombosis and bilateral subdural effusions, as well as extradural fluid collection at T3-T8 level, upon magnetic resonance imaging. Cerebrospinal fluid opening pressure was 50 mmH2O, and a leak was confirmed at C2-C3 level by computed tomography (CT) myelogram. The presence of subdural hematoma precluded anticoagulation treatments. An autologous epidural blood patch at C2-C3 level under CT guidance improved the patient’s condition, remaining free of residual symptoms or recurrence at six-month follow-up
