Coloduodenal Fistula: The Role of MDCT on Diagnosing a Rare Entity

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 [1]. Nevertheless, the clinical presentation may vary significantly - depending on the site of fistulisation - and some cases may never be diagnosed.
