Learning objectives

To elucidate the Radiographic CT and MR Imaging features of Synovial Sarcoma with Radio Pathological correlation -To discuss the importance of Triple Sign for diagnostic characterization of Synovial sarcoma.

Background

Synovial sarcoma is a rare soft tissue neoplasm commonly found in the lower extremity. It is included in the differential diagnosis of all soft tissue masses of the foot and ankle. It has a particular predilection for lower extremity Rad Mantras To remember Synovial sarcoma is a rare soft tissue neoplasm commonly found in the lower extremity. It is included in the differential diagnosis of all soft tissue masses of the foot and ankle. It has a particular predilection for lower extremity Synovial sarcoma is...

Findings and procedure details

Prominent heterogeneity with predominant high signal intensity is also a feature of these lesions on T2-weighted MR images This signal heterogeneity has been described as the triple sign by Jones and co-workers, represented by intermixed areas of low, intermediate, and high signal intensity on long repetition time images). This marked heterogeneity and triple sign on T2-weighted MR images is presumably the result of the mixture of solid cellular elements (intermediate signal intensity), hemorrhage or necrosis (high signal intensity), and calcified or fibrotic collagenized regions (low...

Conclusion

This educational exhibit show cases the imaging features of Synovial Sarcoma and Its differential diagnosis
