An osteoid osteoma in a 19-year-old female was diagnosed with Magnetic Resonance Imaging (MRI). She had an obstinate pain at day-break for 1 year. On physical examination her Lasègue's sign was positive. MRI was performed to discover any lumbar disc herniation, and demonstrated a tumor in the left vertebral arch of the third lumbar spine. The tumor had high signal intensity with a very low signal in the center on the T2-weighted image. The MRI findicgs showed the nidus of the osteoid osteoma.
