title: Peritendinous lesions: the role of high-resolution ultrasonography.
abstract: OBJECTIVE
  To evaluate the peritendinous lesions over the extremities by high-resolution ultrasonography (HRUS).
  
  
  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.
  
  
  CONCLUSIONS
  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.
