Description
Summary:Leiomyosarcomas (LMS) are mesenchymal neoplasms that arise from smooth muscle cells, which less frequently occur in veins. Commonly, leiomyosarcoma accompanied with necrosis and cystic degeneration, which noted as non-enhanced areas on radiological examinations were seen frequently in the literature. We present a rare case of a leiomyosarcoma arising from the inferior vena cava, invading into the right atrium, found accidentally in a 46-year-old male who clinically manifested as progressive dyspnea on exertion. Radiological examinations showed a moderate heterogeneous enhancement tumor followed with foci of non-enhancement area in the central, which was not definitely in line with the pathological findings. The imaging features and differential diagnosis of the tumor are outlined here.
