Kaleidoscopic view of bowel tuberculosis on multi- detector computed tomography (CT) enterography – A novel technique unfolding an archaic disease

Abstract

Gastrointestinal tuberculosis (GI TB) is an important manifestation of abdominal tuberculosis (TB), an extra-pulmonary form of the disease. GI TB commonly affects the small bowel but is difficult to diagnose due to the challenge of evaluating the entire length of overlapping small bowel loops with traditional diagnostic methods like Barium meal follow through, abdominal computed tomography (CT), and endoscopy. New techniques of CT/MR enteroclysis/enterography are now available which specifically image the small bowel. MDCT enterography (MDCTE) is a non-invasive, simple to perform, modified abdominal CT imaging technique permitting reasonably accurate evaluation of the small bowel lumen, wall, perienteric tissues, and solid organs within the abdomen. As GI TB can cause morphological alterations in and around the small bowel, MDCTE seems to be an attractive modality for patients suspected of abdominal or GI TB. As scarce literature is available on MDCTE on tuberculosis, we present a pictorial review on MDCTE findings in patients with GI tuberculosis proved on FNAC and clinical and/or imaging follow-up.
