Spinal subarachnoid hematoma is a very rare disorder with few cases reported in Japan. This disorder may be due to tumor, disorders of vessels, coagulation dysfunctions, trauma or of unknown etiology. We report a case of subarachnoid hematoma with hypertension, in which the cause of the bleeding was not found.A 68-year-old male presented with sudden onset of pain in the bilateral femoral area, and gluteal area. He had a decrease of leg muscularity, and developed urinary retention on November 9, 1993. On admission, spinal MRI showed a space occupying lesion in his spinal canal at L1-L3 and lumbar puncture showed bloody CSF, and developed protein. He was suspected of having a spinal tumor and was transferred to our hospital on November 29. We suspected subarachnoid hematoma, so laminectomy was performed and the hematoma was removed on the same. Post-operatively, he had no pain and urinary retention improved. Two months after surgery, he had made a complete recovery.
