Colo-vesical fistula (CVF) is usually encountered in severe inflammatory and malignant conditions. Radiological imaging is crucial to the diagnosis of a colo-vesical fistula and helps gastroenterologists and surgeons select the best treatment option. This disorder is typically identified during follow-up of treatments for diverticulitis or chronic inflammatory bowel disease. The patients present with symptoms of pneumaturia and fecaluria. The most accurate imaging modality for diagnosing CVF is CT with rectal contrast. In this case report, we present a case of a 58-year-old male patient with complaints of fecaluria and pneumaturia for three months. Ultrasonography and barium enema revealed a clear fistulous tract between the sigmoid colon and the urinary bladder. Subsequently, the patient underwent exploratory laparotomy and the specimen was sent for histopathological evaluation to rule out malignancy. The diagnosis on imaging was consistent with post-operative findings of a CVF. This case report will add to the knowledge of radiologists about the imaging features of CVFs and their identification on imaging.
结肠膀胱瘘（CVF）通常见于严重的炎症和恶性疾病。放射影像学对于结肠膀胱瘘的诊断至关重要，有助于胃肠病学家和外科医生选择最佳治疗方案。这种疾病通常在憩室炎或慢性炎症性肠病的治疗随访期间被发现。患者表现为气尿和粪尿症状。诊断CVF最准确的影像学检查方法是直肠造影CT。在本病例报告中，我们介绍了一名58岁男性患者，主诉气尿和粪尿3个月。超声检查和钡灌肠显示乙状结肠和膀胱之间有一条清晰的瘘管。随后，患者接受了剖腹探查术，并将标本送去进行组织病理学评估以排除恶性肿瘤。影像学诊断与CVF的术后结果一致。本病例报告将增加放射科医生对CVF影像学特征及其影像学识别的认识。
