Pericardial synovial sarcoma.

We report a rare case of a primary synovial sarcoma of the pericardium. Surgical resection was incomplete and chemotherapy and radiotherapy (tomotherapy) were therefore administered. Regular cardiac magnetic resonance imaging scans were used throughout the follow-up, allowing effective planning and application of adjuvant therapies. The survival of our patient was 26 months, substantially longer than most previously reported cases.
