Colonic actinomycosis is rare and can present as an ill-defined intra-abdominal mass that can be difficult to differentiate from colon cancer. This case report aims to share the details of this case and provide diagnostic clues. A 63-year-old female presented with a palpable right-sided abdominal mass. Computed tomography (CT) revealed irregular thickening of the colonic hepatic flexure, and colonoscopy detected no abnormalities. Five months later, the patient returned with an increase in the mass size. Repeat CT revealed lesion expansion, with suspected abdominal wall invasion. Extended right-hemicolectomy with abdominal wall wedge resection was performed, and the histological results were compatible with actinomycosis infection. Colonic actinomycosis is a rare chronic inflammatory disease. Normal colonic mucosa during colonoscopy, with clinical and imaging findings, may help physicians diagnose the condition preoperatively.
结肠放线菌病较为罕见，可表现为界限不清的腹内肿块，难以与结肠癌相鉴别。本病例报告旨在分享该病例的详细情况并提供诊断线索。一名63岁女性因右侧腹部可触及肿块就诊。计算机断层扫描（CT）显示结肠肝曲不规则增厚，结肠镜检查未发现异常。五个月后，患者因肿块增大复诊。复查CT显示病变扩大，怀疑侵犯腹壁。遂行扩大右半结肠切除术及腹壁楔形切除术，组织学结果符合放线菌感染。结肠放线菌病是一种罕见的慢性炎症性疾病。结肠镜检查时结肠黏膜正常，但结合临床和影像学表现，可能有助于医生在术前诊断该病。
