title: Metastatic shoulder liposarcoma to the right ventricle: CT findings.
abstract: Metastatic cardiac liposarcoma is rare. A right ventricular liposarcoma metastasis is described in a 46-year-old man, who was admitted with significant shortness of breath and fatigue, and in whom a large lobulated low attenuation mass occupying most of the right ventricular cavity, with extension through the right ventricular apex and a small-to-moderate pericardial effusion was detected by electrocardiogram-gated cardiac computed tomography. The patient had an antecedent history of a left upper arm liposarcoma treated with surgical resection, chemotherapy, and postoperative radiotherapy 3 years earlier. Surgical resection was performed with the majority of the neoplasm removed though; the right ventricular apex and epicardial extension of tumor could not be fully resected. The histopathologic analysis revealed a liposarcoma, similar to the one resected in the left arm 3 years earlier. Electrocardiogram-gated cardiac computed tomography was able to visualize the metastatic tumor within the heart, accurately evaluate cardiac function and allow for prompt surgical treatment that produced relief of symptoms, and assess for further metastatic disease within the thorax.
