Diagnosis Please Justin Q. Ly, MD Timothy G. Sanders, MD
Case 651 HISTORY A 79-year-old man had a slowly enlarging mass in the left lateral portion of his chest wall. He first noticed the mass 5 years earlier, but he ignored it until he experienced a dull ache localized in the area of the mass. Physical examination revealed a soft-tissue prominence that was firm but lacked discrete margins, associated bruits, or visible discoloration. The patient denied a history of malignancy but reported a history of an enlarged prostate. Conventional radiography, computed tomography (CT), and magnetic resonance (MR) imaging of the chest were performed (Figs 1– 6).
