Abstract
Osteochondroma is one of the most common benign bone tumors, but only 1-4% involve the spine. They make up 0.4% of intraspinal tumors. Herein, we report on a solitary osteochondroma of the lumbar spine presenting with sciatica. A 54-year-old male patient visited our institution, complaining of right leg pain of 2 months duration. His neurological examination revealed a limited right straight-leg-raising test result, motor weakness of right great toe dorsiflexion, and L4-L5 hypoesthesia. Lumbar computerized tomographic (CT) scan and magnetic resonance (MR) imaging studies revealed a tumor mass arising from the inferior articular process of the L3. There was marked improvement of the symptoms after surgical removal of the lesion. Symptoms showed marked improvement after surgical removal of the lesions. Histopathologic examination confirmed the diagnosis of benign osteochondroma.
