Recently we experienced a patient with midline prolapse of intervertebral disc between L2 and L3·We found it was rare according to the literature. The patient was a 32-year-old male who had low back pain, bilateral sciatica and gait disturbance. Myelogram revealed a total block at intervertebral disc between L2 and L3. We thought it was due to the cauda compression by midline prolapse of intervertebral disc between L2 and L3 or to a tumor. During surgery, we found the cauda equina was compressed by midline prolapse of intervertebral disc between L2 and L3. It was completely removed and the symptoms disappeared after operation. It is difficult to distinguish between a midline prolapse of an intervertebral disc at high-level lumbar vertebra and a tumor.
