Actinomycosis is a rare opportunistic bacterial infection. It most commonly affects the cervicofacial area and is less common in the gastrointestinal area. Because of the ambiguous clinical pictures, there is a low preoperative diagnosis rate and a high rate of misdiagnoses. In this case report, we have an unusual presentation of disseminated abdominal actinomycosis in a diabetic male patient with no previous history of surgery or trauma. He presented with abdominal pain for two years. Abdominal imaging showed rectal wall thickening with adhesion and attachment to the bladder, and small bowel with omental and peritoneal deposits, mimicking colorectal cancer with abdominal carcinomatosis. Histopathological examination, however, revealed actinomyces infection with no evidence of malignancy. In such cases, the recovery rate with antibiotic therapy is very high in conjunction with surgical resection.
放线菌病是一种罕见的机会性细菌感染。它最常累及头颈部，在胃肠道较少见。由于临床表现不明确，术前诊断率低且误诊率高。在本病例报告中，我们有一位无手术或外伤史的糖尿病男性患者出现了罕见的播散性腹部放线菌病。他腹痛两年。腹部影像学显示直肠壁增厚并与膀胱粘连，小肠有网膜和腹膜沉积物，类似伴有腹部转移的结直肠癌。然而，组织病理学检查显示为放线菌感染，无恶性证据。在这种情况下，联合手术切除，抗生素治疗的治愈率非常高。
