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.
