目的分析病理证实小肠肉瘤类肿瘤的多层螺旋CT资料,探讨其临床诊断价值。方法36例均做CT平扫,32例增强CT扫描。结果小肠平滑肌肉瘤6例,间质肉瘤11例,原发性小肠淋巴瘤19例。CT扫描均确诊为原发性小肠肿瘤,定位诊断符合率为100%。平滑肌肉瘤的主要CT表现为腔内或腔内外软组织肿块,密度不均匀;间质肉瘤表现为腔外不规则肿块,肿块内有多灶性低密度坏死区或溃疡;淋巴瘤表现为肠壁增厚或肠腔内外息肉状肿块。结论多层螺旋CT能清楚地显示小肠肉瘤类肿瘤的全貌以及病灶与周围脏器的关系,是主要的定位诊断方法,对鉴别诊断有较大的帮助,对指导临床治疗和估计预后有一定的价值。
Objective To analyze the multi-slice spiral CT data of pathologically confirmed small intestinal sarcoma and discuss its clinical value. Methods Thirty-six patients underwent CT scan and 32 patients underwent CT scan. Results Six cases of intestinal leiomyosarcoma, interstitial sarcoma in 11 cases, 19 cases of primary small intestinal lymphoma. CT scan were diagnosed as primary small intestine tumor, the diagnostic accuracy of 100%. The main CT manifestations of leiomyosarcoma is intracavitary or intracavitary soft tissue mass, the density is not uniform; interstitial sarcoma showed extracavitary mass, multifocal low mass necrosis area or ulceration; lymphoma showed increased intestinal Thick or intestine polypoid mass. Conclusions Multi-slice spiral CT can clearly show the overall picture of the small intestine sarcoma tumor and the relationship between the lesion and the surrounding organs. It is the main method of localization diagnosis, which is of great help to the differential diagnosis and has some guidance on clinical treatment and prognosis value.
