%X Lipoblastomas are rare benign tum ors arising from fetal-embryo nal fat that almost always occur in children and about two thirds of them o ccur in the superficial or deep layers of soft tissue on extremities. To our knowledge there ar e only 6 case reports of mediastinal lipoblastomas in the English medical literature. We re port a case of mediastinal lipoblastoma in a 2.5¨Cyear-old child. A mediastinal mass was foun d on the chest x-ray, CT (Computed Tomography)scan and MR (Magnetic Resonance) imaging. We found a fatty density mass with no evidence of septation, strading and soft ti ssue density without enhancement after contrast injection. On MRI, the mass was high-signal intensity on T1 and T2. Complete surgical resection was performed and the pathological examination proved lipoblastoma.
