 A 49-year-old woman suffered hydrocephalus after subarachnoid hemorrhage, and underwent a lumboperitoneal(LP)shunt operation. X-ray imaging revealed that a spinal catheter inserted into the cranial side from L2/3 turned caudally at the Th12 level. Postoperative numbness and pain of the left buttocks and posterior femoral region persisted. The spinal catheter was pulled about 5 cm to improve flexure, and was reconnected 10 months after the shunt procedure. Symptoms improved, but a similar symptom developed one and a half years later. The spinal catheter was torn at the connection to the shunt valve. The catheter curved to the left side of the spinal cord and the catheter tip was located around the right Th12/L1 intervertebral foramen. We continued observations with analgesics, but symptoms did not subside. The shunt was removed 16 months after symptom relapse, and symptoms disappeared immediately. Bent insertion of the lumbar catheter is a potential cause of lower limb neuropathy after LP shunt operation. Attention must also be paid to the continuity of the catheter in follow-up after shunt procedures.
