(a-c) PET scan images demonstrate increased uptake within nodes in the aortic pulmonary window, left hilum, and a mass in the left upper lung. (d) Transesophageal echocardiography shows large cardiac mass invaded to the intra-atrial septum and right and left atrium with cystic lesion protruding to the left atrium. (e-g) MRI with and without contrast shows multiple enhancing neoplastic masses in the muscle compartment in both lower extremities which are believed to be due to metastatic lesions.

The solid component, a 5 x 2.3 cm2 mass, had invaded the basal half of the interatrial septum and the cystic component was found to protrude into the left atrium (Figure 1(d)). Multiple enhancing neoplastic masses in the muscular compartment in both calves were detected on MRI of the lower extremities, which were in favor of neoplastic lesions (Figures 1(e)-1(g)).
