目的:初步探讨艾滋病(AIDS)相关消化道病变的影像学表现。方法:回顾性分析11例AIDS相关消化道病变的影像学表现。行胸部平片检查11例,胸部CT扫描4例,腹部CT扫描9例,盆腔CT扫描2例,盆腔MRI检查1例,消化道内窥镜检查9例。结果:11例中消化道穿孔3例(食管穿孔2例,胃穿孔1例)、肠结核2例、巨细胞性肠炎1例、淋巴瘤4例、胃腺癌1例。食管穿孔的主要影像表现为食管-纵隔瘘伴纵隔淋巴结结核及双肺结核;胃穿孔主要表现为胃瘘伴肝左叶及肝胃间隙脓肿;肠结核主要表现为回盲部肠壁增厚;巨细胞性肠炎主要表现为乙状结肠末段及直肠管壁向心性增厚;淋巴瘤主要表现为受累消化道管壁肿块状增厚,肠腔狭窄或扩张,多伴溃疡及病变周围淋巴结增大;胃腺癌主要表现为胃壁增厚、僵硬及明显强化。结论:AIDS相关消化道病变可表现为多种机会性感染和恶性肿瘤,影像学检查对这些病变的诊断具有重要作用。
Objective: To investigate the imaging manifestations of AIDS-related gastrointestinal lesions. Methods: The imaging findings of 11 AIDS-related gastrointestinal lesions were retrospectively analyzed. Chest radiography in 11 cases, chest CT scan in 4 cases, abdominal CT scan in 9 cases, pelvic CT scan in 2 cases, pelvic MRI examination in 1 case, gastrointestinal endoscopy in 9 cases. Results: 11 cases of gastrointestinal perforation in 3 cases (esophageal perforation in 2 cases, gastric perforation in 1 case), intestinal tuberculosis in 2 cases, 1 case of giant cell enteritis, lymphoma in 4 cases, 1 case of gastric adenocarcinoma. The main imaging findings of esophageal perforation of the esophageal - mediastinal fistula with mediastinal lymph node tuberculosis and tuberculosis; gastric perforation is mainly manifested as gastric fistula with left lobe of liver and liver and stomach interstitial abscess; intestinal tuberculosis mainly for ileocecal intestinal wall thickening; giant The main manifestations of cellular enteritis bowel sigmoid colon and rectum wall concentric thickening; lymphoma mainly manifested as involvement of digestive tract wall thickening, stenosis or expansion of the intestine, with multiple ulcers and lesions around the lymph nodes increased; gastric gland Cancer mainly for the thickened stomach, stiff and significantly enhanced. Conclusion: AIDS-related gastrointestinal lesions can manifest as multiple opportunistic infections and malignant tumors. Imaging examination plays an important role in the diagnosis of these lesions.
