Postpartum bilateral subdural hematomas following spinal anesthesia: case report.

Background: Intracranial subdural hematoma is an exceptionally rare complication of spinal anesthesia. We report a case of this infrequent event and consider the influence of cerebral atrophy as a predisposing factor.

Results: This 18-year-old woman with severe headaches was admitted to the hospital 42 days after delivery. She had a history of normal pregnancy and uneventful labor and delivery. The epidural anesthesia was satisfactory. Computed tomography showed bilateral chronic subdural hematomas that were surgically removed. An early follow-up scan showed marked resolution of the hematomas and a small sized brain with large subarachnoid space. A late follow-up scan confirmed the diagnosis of brain atrophy.

Conclusions: Persistence of headache and gradual progression despite treatment must be regarded as a sign of intracranial complication following spinal anesthesia. In this case, cerebral atrophy is considered to be a contributory factor for the development of subdural hematoma following dural puncture.
