Abstract:
The most common symptoms of primary gastrointestinal (GI) lymphoma are non-specific, such as nausea, vomiting, diarrhea, weight loss, and abdominal pain. The rare acute symptoms include bowel obstruction, intussusception, and perforation. Primary small bowel lymphoma accounts for the smallest proportion of all GI malignancies. We report a case of intestinal lymphoma presenting with bloody stools and anemia. The patient initially underwent both duodenoscopy and colonoscopy with negative findings. Isotopic red blood cell (RBC) scan was then performed due to persistent bleeding along with computed tomography angiography (CTA) because of suspected bleeding in the left abdomen. Successful embolization over the arcade of the sigmoid and left colic arteries was performed. However, the bleeding did not stop, and ischemic colitis was diagnosed by repeat colonoscopy. A coloenteric fistula was finally discovered during emergent laparotomy. This is a rare condition that has not been previously described in Taiwan. Early diagnosis and timely management will decrease morbidity and mortality in the GI lymphoma population.
