Cerebellar hemorrhage is a rare complication of spinal anesthesia. We report a case in a 51-year-old woman with a history of hypertension who underwent uterine dilatation and curettage with spinal anesthesia. During recovery she vomited and complained of headache. Postdural puncture headache was diagnosed. When there was no response to conventional treatment, computed tomography and magnetic resonance scans of the head were performed. The scans confirmed cerebellar hemorrhage due to rupture of a cavernous angioma. The patient recovered fully without surgical decompression. We review the pathogenesis of headache and cerebral hemorrhage after spinal anesthesia and propose differential diagnosis between spontaneous rupture related to hypertension and cerebrospinal fluid hypotension syndrome caused by trauma from lumbar spinal puncture. Patients with prolonged severe headache after spinal anesthesia require neurologic and radiologic monitoring to rule out the possibility of intracranial complications.
