Thymolipoma

Case contributed by Dr John Bui

Presentation

Abnormal CXR

Patient Data

Age: 67
Gender: Female
CT

Anterior mediastinal mass of heterogeneous density with extensive areas of internal fat. Differential diagnosis again includes thymolipoma and germ cell tumor with lymphoma less likely.

MRI

The previously demonstrated anterior mediastinal mass contains multiple areas of high signal in both T1 and T2-weighted sequences that suppress fat saturated images, compatible with macroscopic fat. The rest of the mass demonstrates homogeneous enhancement.

Case Discussion

The presence of fat within the anterior mediastinal mass would be most suggestive of a thymolipoma.
