Answer

Ultrasonography does not play a significant role in the evaluation of synovial sarcomas. The imaging characteristics cannot be used to establish a precise diagnosis. Grossly, sonograms can provide information regarding the size and consistency of a soft-tissue mass (eg, differentiating cystic from solid masses or a localized mass from diffuse edema). Most commonly, a well-circumscribed, heterogeneous mass, with or without cystic components, is seen.

Ultrasonography can be useful as a real-time imaging technique for guiding diagnostic needle biopsy, especially in large heterogeneous tumors. Color-flow Doppler ultrasonography reveals blood flow in solid soft-tissue masses. [26]  Studies have shown that findings in color-flow Doppler ultrasonography are not specific for differentiating benign from malignant tumors; however, the technique may be useful for monitoring the regression of tumor neovascularity after the administration of chemotherapy or irradiation.
