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.
