1. Synovial sarcoma (SS) occurs in the extremities and trunk in young adults and has indolent presentation mimicking benign tumor. 2. Extremity SS is best characterized on MRI as lobulated heterogeneously enhancing mass with characteristic imaging features such as ‘triple sign’, ‘bowl of grapes’ appearance and fluid levels. 3. Non-extremity synovial sarcomas can occur anywhere in the trunk. Intrathoracic SS is often pleural-based at presentation, and may represent a distinct entity called pleuroparenchymal syovial sarcoma (PPSS). 4. Pleural-based metastases are the most common sites of metastatic disease. 5. Synovial sarcomas are relatively sensitive to chemoradiotherapy in both neoadjuvant and adjuvant settings, and radiologists play a key role in assessing response.  

1. Review the pathophysiology, classification, clinical features and management of synovial sarcomas 2. Illustrate the multimodality imaging features including CT, MRI, PET/CT of primary and recurrent extremity and non-extremity synovial sarcoma, 3. Discuss the prognostic implications of various radiologic findings and evaluation of treatment response after neoadjuvant therapy  4. Review the metastatic pattern of synovial sarcomas with focus on their predilection for pleural-based disease
