Nonneoplastic conditions presenting as soft-tissue tumors: pictorial review

Review of referrals to our unit over the last 7 years showed that, of approximately 750 cases referred as soft tissue tumours, 132 were subsequently diagnosed as nonneoplastic lesions. The imaging characteristics of these lesions are presented to differentiate them from neoplasms. The most common diagnoses were myositis ossificans, ganglion cyst, abscess/infection, bursitis, and synovitis. The imaging features of other rarer conditions will also be discussed.
