Images of Spine Care Osteoid osteoma leading to sciatica A 20-year-old man had a 2-year history of low back pain radiating to the right buttock and leg. He was misdiagnosed by the local clinic to have lumbar disc herniation. His pain was partially relieved by non-steroidal antiinflammatory medications. Physical examination revealed tenderness at the L5 level. Right straight leg raise test was 45°. Plain radiograph showed indistinct lesion at L5 (Figure A). Computed tomography showed a lytic nidus surrounded by a margin of dense sclerotic rim located in the right lateral recess and the intervertebral foramen of L5 (Figure B, C, D). Magnetic resonance imaging revealed a low T2 intensity circular lesion located in the right lateral recess and the intervertebral foramen of L5 (Figure E, F). Tissue biopsy found osteoid osteoma.

Figure. (A) Plain radiograph showed indistinct lesion at L5 (black arrow). (B, C, D) Computed tomography showed a ring-like nidus surrounded by a margin of dense sclerotic bone located in the right lateral recess and the intervertebral foramen of L5. (E, F) Axial and sagittal magnetic resonance imaging on T2weighted images showed a low T2 intensity circular lesion located in the right lateral recess and the intervertebral foramen of L5.
