Osteoid osteomas of the spine are benign bone tumors typically presenting with progressive pain without neurological deficit. This report presents a case of an osteoid osteoma in the lumbar spine associated with radicular pain. The patient, a young male athlete, presented with severe chronic nightly left low-back pain radiated to the ipsilateral lower extremity who failed to respond to physical therapy and analgesic medications. ⋯ A selective L3 nerve root block provided significant relief. Surgical excision of the osteoid osteoma resolved the symptoms. This case emphasizes the importance of early suspicion and diagnostic interventions in the detection and treatment of osteoid osteoma.
