In France, tuberculosis (TB) is still a health issue among underprivileged people and immigrants. We report a case of disseminated tuberculosis with intestinal involvement causing ill absorption and thus, making oral treatment impossible. Intestinal TB is often underrated and yet, malabsorption may lead to treatment failure or to developing antibiotic resistance. This type of tuberculosis must be systematically investigated when assessing the damage caused by tuberculosis and, more particularly, if there is any abdominal pain as well as clinical and biological signs of malabsorption. Parenteral antibiotherapy and nutrition must be systematically discussed.
