【摘要】：目的:探讨艾滋病合并消化道恶性肿瘤的CT表现。方法:回顾性分析10例艾滋病合并消化道恶性肿瘤的影像资料,结合相关文献总结消化道肿瘤的CT特点。结果:1例卡波西肉瘤累及直肠,肠壁环形增厚,强化明显,无肿大淋巴结。5例淋巴瘤中3例以多节段弥漫性浸润为主,管壁环形增厚,管腔狭窄不明显,1例为局灶浸润,1例局灶浸润伴腔内结节状突起;5例均有腹膜后增大淋巴结,其中4例同时伴系膜淋巴结增大,4例增强轻度强化,1例明显强化。4例胃肠道腺癌中3例表现为局灶突起结节,明显强化,管腔狭窄,灶周见增大淋巴结。结论:艾滋病合并消化道恶性肿瘤的CT表现具有一定的特征,能够为其诊断及鉴别诊断提供重要依据。
[Abstract]:Objective: to investigate the CT findings of AIDS complicated with digestive tract malignant tumor. Methods: the imaging data of 10 cases of AIDS complicated with digestive tract malignant tumor were analyzed retrospectively, and the CT features of digestive tract tumor were summarized. Results one case of Kaposi's sarcoma involved the rectum. The intestinal wall was thickened and enhanced obviously. In the 5 cases of lymphoma without enlarged lymph nodes, 3 cases were characterized by multilevel diffuse infiltration, and the wall of the intestine was thickened in a circular way. The stenosis of the lumen was not obvious in 1 case with focal invasion and 1 case with intraluminal nodular protuberance. All 5 cases had retroperitoneal enlarged lymph nodes. Among them, 4 cases were accompanied by enlargement of Mesangial lymph nodes, 4 cases with enhanced slight enhancement and 1 case with obvious enhancement of 4 cases of gastrointestinal adenocarcinoma. 3 cases showed focal protuberant nodules, obvious enhancement, stenosis of lumen, enlarged lymph nodes around the foci. Conclusion: Ct findings of AIDS complicated with digestive tract malignant tumor have certain characteristics, which can provide important basis for diagnosis and differential diagnosis.
