Computed tomography and sonography of thymolipoma.

Thymolipoma is a rare benign tumor of the thymus. Because of its large size and pliability, the mass usually drapes itself around the heart, conforming to its borders and producing a large radiographic shadow easily mistaken for cardiomegaly. The diagnosis rarely has been made preoperatively. A unique case diagnosed by computed tomography (CT) and sonography before surgery is reported.
