{Abstract}: <B>UNASSIGNED: </B>Malignancy can lead to colo-enteric fistulas. A malignant fistula between the rectum and the jejunum is a rare occurrence.<BR><B>UNASSIGNED: </B>A 60-year-old female suffered from diarrhea, vomiting, and epigastric pain for 4 months. After demonstration of a dilated rectum with heterogeneous collection on ultrasonography, contrast-enhanced computed tomography (CECT) along with rectal contrast was done, which showed heterogeneously enhancing asymmetrical circumferential thickening of the proximal rectum, including rectosigmoid junction, collection in the rectum and two recto-jejunal fistulous tracts. Colonoscopy showed ulcero-proliferative growth in the rectum with two fistulous tracts communicating with the jejunum. Biopsy from the growth indicated a poorly differentiated adenocarcinoma. Conservative and palliative treatment was provided.<BR><B>UNASSIGNED: </B>Clinical features of colo-enteric fistulas can include abdominal pain, diarrhea, and weight loss. The patient may be asymptomatic in some cases. Options for diagnosis include barium studies, enteroscopy, colonoscopy, CECT, and computed tomography enterography (CTE). Malignant bowel fistula is associated with serious complications resulting in high morbidity and mortality rates. Surgical resection and fistula repair are the mainstay of curative treatment.<BR><B>UNASSIGNED: </B>Long-standing gastrointestinal symptoms like chronic diarrhea in the elderly should be investigated with imaging modalities like CECT. Early detection with imaging can reduce debilitating metabolic and nutritional deficiencies and improve patient's morbidity and mortality.
