title: Large spinal meningioma with hemorrhage after selective root block in the thoraco-lumbar spine.
abstract: Spinal meningioma accounts for 25% of all spinal cord tumors and occurs mostly in the thoracic region. Spontaneous intraspinal bleeding associated with spinal meningioma has rarely been reported. Most cases of hemorrhage associated with meningiomas are extratumoral and subarachnoid, whereas subdural and intratumoral hemorrhage cases have been reported to occur rarely. We experienced a case of a 58-year-old woman with thoracolumbar spinal meningioma accompanied by intraspinal subdural hematoma. She presented with progressively worsened back pain and newly developed weakness in the right lower extremity after a selective nerve root block in the lumbar spine. She underwent the operation and progressively showed neurological recovery during the postoperative course. We report a thoracolumbarspinal meningioma with subdural and intratumoral hemorrhage after a spinal procedure that caused a sudden neurological deterioration.
