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., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Ladke et al.)

Teaching Point: Sigmoid diverticulitis may cause colo-vesical fistula from which intravesical protrusion of a pedunculated colonic polyp is an exceptional event that should not be regarded as a bladder cancer., Competing Interests: The authors have no competing interests to declare., (Copyright: © 2020 The Author(s).)

Introduction: Colo-vesical (CV) fistulae are the most common type of fistulae associated with diverticular disease. Surgery remains the mainstay of treatment, without which, CV fistulae rarely achieve complete healing., Presentation of Case: Herein, we report the case of a 62-year-old man who developed a CV fistula after reversal of Hartmann's procedure (initially for management of diverticular abscess), which healed with conservative management alone., Discussion: We discuss possibilities of the aetiology of this fistula. The CV fistula may have been initially present, which came to light only after his reversal. Or an iatrogenic fistula that developed at the time of reversal of Hartmann's., Conclusion: This is the first time that such a fistula has been demonstrated clinically and radiologically to have healed spontaneously without surgery. We recommend that conservative management of CV fistulae should be considered., (Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.)
