【摘要】 目的：分析42例常見小腸肉瘤MSCT征象，探討其診斷及鑒別診斷價值 。方法： 42例中38例做增強掃描。結果：小腸平滑肌肉瘤8例，間質肉瘤13例，原發性小腸淋巴肉瘤21例。CT掃描均診斷為原發性小腸腫瘤，定位診斷符合率為100%（42/42）；平滑肌肉瘤呈腔內或腔內外軟組織腫塊；間質肉瘤主要表現為腔外不規則腫塊，腫塊內常伴多發性低密度影；淋巴肉瘤表現為明顯的腸壁增厚或腸腔內外息肉狀腫塊。結論：MSCT可明確小腸肉瘤的部位和范圍，病灶與周圍結構的關系，定位診斷正確，是診斷及鑒別診斷較有價值的方法。

Abstract Objective To investgate value of multi-slice CT in diagnosing common small intestinal sarcoma. Methods Imaging findings of multi-slice CT in 42 cases with small intestinal sarcoma were analyzed. Plain CT scanning was performed in all 42 cases and enhancement in 38 cases. Results The tumor included leiomyosarcoma in 8 cases, mesenchymosarcoma in 13 cases and primary small intestinal lymphoma in 21 cases. CT scans confirmed primary small intestinal tumors,with an accuracy of 100%(42/42) in the determination of the location.The main signs of CT scans included intra or both intra-and extra-luminal soft tissue mass in leiomyosarcoma; extra-luminal irregular masses and multiple areas of low density in mesenchymosarcoma; bowel-wall thickening or luminal polypoid mass in lymphoma. Conclusion Multi-slice CT could show intestinal sarcoma clearly and its relation with other organs. It is the major imaging method of the location and is also very helpful in diagnosisand differentiating diagnosis.
