To check the value of computed tomography (CT) in the diagnosis of cytomegalovirus (CMV) infection of the intestine, CT findings in ten patients with coloscopically proven CMV infection were reviewed. All patients were chronically ill men with AIDS. In nine of the ten cases CT scans of the small intestine and/or colon disclosed abnormalities. The predominant alteration (9/9) was a symmetric wall thickening in the bowel segments involved (10-30 mm). The location and extent showed good agreement with the inflammatory areas seen on coloscopy. The cecum and terminal ileum were the regions most frequently affected. In seven of the nine patients with CT abnormalities CT revealed pericolonic inflammation, particularly around the cecum. Lymph nodes were increased but not enlarged. Comparison of the findings in intestinal CMV infection with those in other AIDS-related diseases suggests that CT may be to limit the differential diagnosis. Abdominal CT serves as suitable primary imaging modality for the initial evaluation of patients with AIDS and abdominal symptoms of unknown etiology.
为了检查计算机断层扫描（CT）在诊断肠道巨细胞病毒（CMV）感染中的价值，回顾了10例经结肠镜检查证实为CMV感染患者的CT表现。所有患者均为患有艾滋病的慢性病男性。10例中的9例小肠和/或结肠CT扫描显示异常。主要改变（9/9）是受累肠段对称的肠壁增厚（10 - 30毫米）。其位置和范围与结肠镜检查所见的炎症区域吻合良好。盲肠和回肠末端是最常受累的区域。9例CT异常的患者中有7例CT显示结肠周围炎症，尤其是盲肠周围。淋巴结增多但未肿大。将肠道CMV感染的表现与其他艾滋病相关疾病的表现进行比较表明，CT可能有助于限制鉴别诊断。腹部CT是对患有艾滋病且有不明病因腹部症状的患者进行初步评估的合适的主要影像学检查方法。
