The ileocecal region is the most common site of
tuberculosis in the gastrointestinal tract. The common
imaging findings include thickening of the ileocecal valve
and adjacent ileum and colon.
At CT, mesenteric lymphadenopathy with low attenuation

soft -tissue attenuation nodes occasionally occur, colonic
tuberculosis can take several forms, including segmental
ulceration, inflammatory strictures, and hypertrophic
lesions that resemble polyps and masses.
