We reported a case of osteochondroma in a lumbar intraspinal lesion. Osteochondromas are most commonly located in the extremities. It is rare in the spinal region.
The patient was a 43-year-old man with right coxalgia and numbness of medial right thigh. There was no sign of disease in his right hip joint. MRI and CT imaging revealed a mass lesion occupying the spinal canal at the L2 to L3 levels, which had compressed the dural tube. Complete resection was performed as a microscopic surgical technique in 2004. At surgery, a firm and cartilaginous tumor originating from the facet joint was radically excised. After surgery the patient's neurological deficit had resolved. Histological examination revealed that the lesion was osteochondroma. Such lesions are rare in the lumbar spine and osteochondroma arising from the lumbar facet joint is unique.
