33 year old male with a history of synovial sarcoma of the left wrist s/p resection and radiation therapy. The field-of-view was increased to include the distal forearm. Foci of metallic susceptibility artifact are noted along the ulnar aspect of the wrist compatible with prior synovial sarcoma resection.We see no mass lesion to suggest tumor recurrence. Again seen is reticulation of the subcutaneous fat along the ulnar aspect of the forearm and wrist which appears to have decreased slightly when compared to the prior examination. There is mild edema and enhancement of the pronator quadratus muscle and extensor digitorum muscle which may reflect prior radiation therapy changes, appearing similar to the prior study. The extensor and flexor tendons appear intact.
Posttreatment changes following synovial sarcoma resection without evidence of tumor recurrence.
