Liposarcomas of the mediastinum

Primary Retroperitoneal Myxoid Liposarcomas

Myxoid liposarcomas (MLSs) are genetically defined by the presence of DDIT3 gene fusions and most commonly arise in the extremities of young adults. Whether MLSs develop primarily in the retroperitoneum is controversial, and a recent retrospective study found no molecularly confirmed examples. Because MLSs tend to metastasize to deep soft tissues, purported examples of primary retroperitoneal l...

Imaging of the Mediastinum

Mediastinal masses can be benign cysts, neurogenic tumors, germ cell neoplasms, thymomas or lymphomas. The mediastinum is demarcated by the pleural cavities laterally. Superior to the mediastinum, you find the thoracic inlet. The mediastinum is usually divided into three main compartments, anterior, middle and posterior. This anatomical classification of the mediastinum is useful for the radiol...

Haemangioma of the mediastinum.

Mediastinal masses not infrequently present themselves as problems for diagnosis. Benign vascular tumours of the mediastinum are rare. Adams and Bloch (1944) reported a case in which the tumour was incompletely removed at operation. The patient was alive and well four years later. The subject was reviewed by Seybold, McDonald, Clagett, and Harrington (1949), who collected 14 cases from the lite...
