I report here a case of a posterior horn syndrome presumably due to sacral cord injury during the procedure of epidural anesthesia. A 43-year-old female underwent hysterectomy for myoma uteri. The operation was initially planned to be performed under epidural anesthesia. When a needle was inserted at the level of Th 12/L 1, she felt severe pain in the medial aspect of the left thigh. After the operation under general anesthesia, intolerable pain continued in the buttocks, the medial aspect of the left thigh, and the posterolateral aspect of the left lower leg. Lumbar MR images demonstrated slight disc hernia but no intra- and extramedullary hematomas. Seven weeks after the operation, she was referred to my clinic for neurologic evaluation. Motor functions were intact. Knee jerks on both sides were hyperactive; other tendon reflexes were normal. Plantar reflexes were indifferent. Thermal and pin-prick sensations were lost in the left S1 dermatome, and moderately impaired in the left S2 dermatome. Light touch and vibration sense showed no remarkable changes. Her sensory disturbance could have been caused by a lesion involving the left posterior horn and lateral spinothalamic tract within the S1 segment of the spinal cord.

A 70-year-old outpatient presented with a chief complaint of sudden left leg motor weakness and sensory disturbance. He had undergone L4/5 posterior interbody fusion with L3-5 posterior fusions for spondylolisthesis 3 years prior, and the screws were removed 1 year later. He has been followed up for 3 years, and there had been no adjacent segment problems before this presentation. Lumbar magnetic resonance imaging (MRI) showed a large L2/3 disc hernia descending to the L3/4 level. Compared to the initial MRI, this hernia occurred in an "intact" disc among multilevel severely degenerated discs. Right leg paresis and bladder dysfunction appeared a few days after admission. Microscopic lumbar disc herniotomy was performed. The right leg motor weakness improved just after the operation, but the moderate left leg motor weakness and difficulty in urination persisted.
