CTICasesMediastinal Liposarcoma with Right Heart Compression
Imaging findings
Chest CT shows a massive, multi-lobulated, fat-attenuating anterior mediastinal mass with nodular soft-tissue components and thick internal septations. The tumor causes severe posterior displacement and compression of the right atrium and right ventricle.
Key takeaways
Massive mediastinal liposarcomas can cause life-threatening right heart inflow tract obstruction. Surgical resection of these highly adherent tumors carries a high risk of fatal mechanical complications, including inadvertent tearing of the thin right ventricular free wall during dissection.
