Cytomegalovirus (CMV) pseudotumour of the gastrointestinal tract, is a rare benign entity which is treated with antiviral medications and known to resolve spontaneously in a few cases. This is a case report of a 58-year-old man who presented with right lower quadrant abdominal pain. Contrast enhanced computerized tomography of abdomen and pelvis showed apple core lesion involving proximal transverse colon, ceacum, ascending colon, ileoceacal valve and terminal ileum. Synchronous carcinoma of colon was suspected. At laparotomy, there was growth palpable only in the proximal transverse colon. Histological findings of biopsy specimen revealed CMV pseudotumour. CMV pseudo tumour should be included in the differential diagnosis of apple core lesions of the colon even in immunocompetent adults. Endoscopy and biopsy are strongly recommended before surgery in colonic mass lesions to make a definitive diagnosis and to avoid unnecessary surgery.
胃肠道巨细胞病毒（CMV）假瘤是一种罕见的良性病变，采用抗病毒药物治疗，已知少数病例可自行消退。本文报告一例58岁男性，表现为右下腹腹痛。腹部和盆腔增强计算机断层扫描显示“苹果核”样病变累及近端横结肠、盲肠、升结肠、回盲瓣和末端回肠。怀疑同时存在结肠癌。剖腹手术时，仅在近端横结肠可触及肿物。活检标本的组织学检查结果显示为CMV假瘤。即使在免疫功能正常的成年人中，CMV假瘤也应纳入结肠“苹果核”样病变的鉴别诊断。对于结肠肿块性病变，强烈建议在手术前进行内镜检查和活检，以明确诊断并避免不必要的手术。
