Peritendinous lesions: the role of high-resolution ultrasonography.

PURPOSE: To evaluate the peritendinous lesions over the extremities by high-resolution ultrasonography (HRUS).

MATERIALS AND

METHODS

The authors retrospectively collected 328 cases, focusing on peritendinous lesions in limbs. The diagnosis was made by US findings with long-term follow-up, aspiration and biopsy proved.

RESULTS

The most common disease entity in our study is ganglion (n=270), followed by Baker's cyst (n=24). Other disease entities included tenosynovitis, bursitis, gout, hematoma, amyloidosis, thrombophlebitis, and other tumor/tumor-like lesions, such as osteogenic sarcoma (OGS), schwannoma, lymphoma, myxoid lipomsarcoma, xanthoma, intramuscular cavernous hemangioma, pigmented villonodular synovitis (PVNS), giant cell tumor of the tendon sheath (GCTTS), etc.

CONCLUSION

Because of dynamic capabilities and aid of real-time sono-guided fine needle aspiration, HRUS becomes an efficient and inexpensive tool for musculoskeletal lesions, especially in the superficial parts.
