CONCLUSION
ITB and CD are similar chronic granulomatous diseases, posing a real diagnostic problem. We reported two observations showing an initial diagnostic error in the context of inflammatory ileo-colitis which was almost fatal for our patients due to the spread of tuberculosis after corticosteroid therapy. It is essential to differentiate the 2 pathologies because of the therapeutic implications of CD, which can lead to an explosion of tuberculosis symptoms. To date, the diagnosis of ITB remains difficult to achieve in Madagascar. Treatment of ITB should be medical and conservative. Only the complicated forms should resort to surgery.
