Graft pseudoaneurysm simulating desmoid tumor recurrence.

A desmoid tumor is a rare neoplasm of soft tissues and, although benign, is locally invasive and tends to recur. We report a case of suspected recurrence of a supraclavicular desmoid tumor that had been resected 2 years earlier. Computed tomography suggested the correct diagnosis of a pseudoaneurysm of a venous graft that had been placed during the resection.
