Abstract
A six‑year‑old girl presented with a left‑sided abdominal mass and a non‑functioning left kidney, initially diagnosed radiologically as Wilms’ tumor. Intraoperatively, the kidney was found to be compressed—not invaded—by a massive, benign‑appearing retroperitoneal tumor. The mass was excised with preservation of the kidney. Unrecognised extension of the tumor through the lumbar intervertebral foramen resulted in a postoperative spinal epidural hematoma, causing acute paraparesis. Emergency lumbar decompression was performed, with partial neurological recovery. This case highlights the diagnostic challenge posed by giant dumbbell neurogenic tumours and the importance of preoperative spinal imaging when retroperitoneal masses abut the vertebral column.
