Info

A 55×40 mm destructive mass is noted at the manubrium of the sternum that shows inhomogeneous enhancement on post contrast images. The mass infiltrates adjacent soft tissue structures and bulges into the superior mediastinum.

A 10mm hypodense lesion is noted in imaged portions of the upper abdomen at the liver. 

Case Discussion

Pathology proved sternal osteosarcoma, a relatively rare entity, most often seen in elderly patients, mainly due to previous radiation therapy.
