Mediastinal neoplasms of mesenchymal origin are rare, accounting for less than 6% of these tumors. Most of these tumors are liposarcomas, although cystic lesions are uncommon. The authors present a case of a 58-year-old woman with progressively worsening dyspnea since she was 52-years-old. Laryngeal stridor was auscultable and a chest CT scan showed a cystic lesion in the posterior mediastinum. The tumor was resected and the histological examination revealed myxoid liposarcoma.
