Intracranial rebleeding post spinal anesthesia in pregnant patient with undiagnosed chronic subdural hematoma: case report.

Intracranial hematoma after spinal anesthesia is a rare complication. It generally presents with posture-dependent headache that becomes persistent. We describe the case of patient submitted to spinal anesthesia for cesarean section who presented a non-posture-dependent headache, resistant to clinical treatment, that progressively worsened and with symptoms of intracranial hypertension. The patient had a history of head trauma without symptoms. The CT-scan revealed a chronic bilateral parietal hematoma with a recent bleeding component, treated surgically. We concluded that spinal puncture led to chronic hematoma to rebleed. We have reported the case to draw attention to the importance of investigating atypical headache after spinal anesthesia.
