Immune reconstitution inflammatory syndrome to tuberculosis (TB-IRIS) is an inflammatory response to infection that arises following restoration of the immune system and is increasingly recognized as a risk in patients treated with tumor necrosis factor α inhibitors who develop active tuberculosis infection. We present the case of a 19-year-old man treated with adalimumab for Crohn's disease who presented with disseminated miliary tuberculosis. His treatment course was complicated by central nervous system TB-IRIS following cessation of his immunosuppression. We review the presentation and differential diagnosis of TB-IRIS, as well as risk factors for developing IRIS and the treatment of IRIS in this population.
