Primary mediastinal giant synovial sarcoma: A rare case report

Abstract

Synovial sarcoma has been defined by the World Health Organization (WHO) in 2002 as a type of mesenchymal tissue cell tumor that exhibits epithelial differentiation and represents the third most common soft-tissue sarcoma in adults, accounting for approximately 10% of soft-tissue sarcomas. To date, only few reports have focused on mediastinal synovial sarcoma imaging findings. Herein, we report a case of a 13 cm primary mediastinal giant synovial sarcoma, diagnosed in a 56-year-old patient admitted in our Department of Radiology with a six-month history of dyspnea and back pain.
