Coloduodenal fistula is a very infrequent complication, which can arise from both benign and malignant diseases. It consists in a pathological communication between the lumen of the colon and duodenum. The onset of signs and symptoms is generally sub-acute, and the majority of the patients will present with a non-specific abdominal pain, diarrhoea, nausea and vomiting . Nevertheless, the clinical presentation may vary significantly - depending on the site of fistulisation - and some cases may never be diagnosed.
When not clinically suspected, cross-sectional imaging studies can be the only tool to suggest the diagnosis and provide information necessary for deciding among therapeutic options . In this article, we report a case of coloduodenal fistula arising from a colonic malignancy, diagnosed by multi-detector computed tomography scan (MDCT). A brief discussion regarding the condition and its diagnostic challenges is presented.
