Pericardial Synovial Sarcoma Followed Up With Contrast-Enhanced PET-CT
Pericardial synovial sarcoma is an extremely rare tumor, and a challenging diagnosis due to nonspecific diverse presentation requiring a very strong clinical acumen along with an aggressive multimodal approach. Histopathological confirmation remains the gold standard. The optimal management is unclear because of very few cases reported in literature. Herein, we describe the findings on contrast-enhanced FDG PET-CT facilitating the staging, lesion characterization, and timely response assessment to chemotherapy.
