Telangiectatic osteosarcoma is a rare variant of osteosarcoma, most commonly diagnosed in long bones. Its occurrence in the lumbar spine with retroperitoneal extension is extremely rare and poses a significant diagnostic challenge. We present the case of a 14-year-old girl with a left lumbar mass, whose imaging revealed a large lesion centered on L3. Histological confirmation established the diagnosis of TOS. This case highlights the importance of a thorough clinical and diagnostic approach for these atypical presentations to optimize therapeutic management.
