A boy aged seventeen years old student admitted to our hospital suffering from low back pain, radiation pain to his left leg and sensory disturbance on the same region.Radiograph showed that the 4th lumbar vertebral body and arch had thin cortex and elliptical bulging. Myelogram and angiogram revealed compression of the 5th lumbar nerve root and meandering of the 4th lumbar artery without vascularization and blood pooling. We suspected giant cell tumor of bone, aneurysmal bone cyst and solitary enchondroma.At the time of the surgery, the tumor had pink-yellowish semipermeable substance beneath the thin cortex macroscopically. Therefore we diagnosed enchondroma and performed partial laminectomy and replacement of the vertebral body. Histological diagnosis was benign enchondroma.Eight months after operation, he is going to school without disability. We have had satisfactory result of grafted bone with good condition in roentogenogram.We reported one rare case with a few literary consideration.
