Imaging and Clinical Findings in a Series of Six Cases of Rare Primary Mediastinal Liposarcoma.

Primary mediastinal liposarcoma is a rare, fat-containing malignant lesion that can manifest incidentally with varied imaging appearances. The size and location within the mediastinum can vary among patients. Here, the authors describe the clinical presentation, radiographic characteristics, management, and prognosis in a series of six patients with primary mediastinal liposarcoma. The following case series suggests that even simple-appearing fatty intrathoracic lesions may lead to the development of malignant imaging features.
