软组织肉瘤占恶性肿瘤的1%,最常见的发病部位为下肢。这些肿瘤具有高度复发的趋势,单纯切除术后的局部复发率仍占90%,整体切除术后的复发率约30%。以前曾复发的肿瘤在手术后的局部复发率更高。作者分析了21例软组织肉瘤患者手术后的26个MR和US表现,均发生于肢体,计有:MFH5例,滑膜肉瘤5例,上皮样肉瘤3例,未分类肉瘤2例,纤维肉瘤2例,多形性肉瘤1例,血管外皮瘤1例,脂肪肉瘤1例,神经上皮瘤1例。26例中,10例MR显示了肿瘤复发(均经组织学证实),
Soft tissue sarcoma accounts for 1% of malignant tumors, the most common site of attack is the lower extremities. These tumors have a high tendency to relapse. The local recurrence rate after simple resection still accounts for 90%, and the recurrence rate after total resection is about 30%. Tumors that had previously relapsed had a higher rate of local recurrence after surgery. The authors analyzed 26 MR and US manifestations of 21 cases of soft tissue sarcoma after surgery, all occurring on the limbs, including: 5 cases of MFH, 5 cases of synovial sarcoma, 3 cases of epithelioid sarcoma, 2 cases of unsorted sarcomas, and 2 cases of fibrosarcoma. For example, one case of pleomorphic sarcoma, one case of hemangiopericytoma, one case of liposarcoma, and one case of neuroepithelial neoplasia. Of the 26 cases, 10 cases showed tumor recurrence (all confirmed by histology).
