A rare case of spinal dysraphism of which symptomatic onset had been in adulthood was reported.A thirty-Seven years old male had consulted our out-patient service with complaint of dysesthesia in his left leg. Physical examination revealed a small dimple of his skin, hairly patch and lumbosacral lipoma on his back. Plain X-ray showed spina bifida from the fourth lumbar vertebra to the sacrum. During observation at the out-patient service, dysesthesia was deteriorated up to the L4 dermatome.Spinal exploration was noted to continue deeply into the subarachnoid space by a fibrous band, and to connect to the intraspinal lipoma on the low placed connus medullaris. Conus medullaris and cauda equina were seen to be pulled dorsally by the fibrous band, which was cut to free spinal cord from tension. Postoperatively dysesthesia in the leg improved.
