RESUMO
Recurrence of a soft tissue sarcoma typically manifests as a round or oval mass at imaging, and recurrent high-grade soft tissue sarcomas generally enlarge relatively rapidly. We present a case of high-grade undifferentiated pleomorphic sarcoma in the calf of a 48-year-old male that recurred as a thin, curvilinear "tail" of enhancing tissue at magnetic resonance imaging (MRI), with extremely indolent growth over a 7-year period. The unusual imaging finding of a slowly enlarging "tail" should not be dismissed as postoperative changes, even for a high-grade soft tissue sarcoma.

Stress injury to the distal humerus has been reported as a cause of chronic arm pain among competitive tennis players. As the serve is technically similar to an overhead throwing motion, it is conceivable that this injury could occur in other overhead athletes. Overuse injuries, including rotator cuff tears, ulnar collateral ligament injuries, and joint sprains have routinely been reported in quarterbacks, but there are few reported cases of upper extremity bony stress injuries in these athletes. Magnetic resonance imaging aids in the diagnostic evaluation of an upper extremity injury as it can identify numerous structural injuries and early stress changes within bone. Accurately diagnosing stress reactions helps prevent progression toward stress fracture, which is possible if conservative measures are initiated early in the rehabilitation period. In this article, we report the case of an elite college quarterback who presented with localized elbow pain while throwing.
