Abstract: © Turkish Society of Radiology 2015. Immune reconstitution inflammatory syndrome (IRIS) is a consequence of exaggerated and dysregulated host’s inflammatory response to invading microorganism, leading to uncontrolled inflammatory reactions. IRIS associated with tuberculosis (TB) is well recognized among human immunodeficiency virus (HIV)-infected patients receiving highly active antiretroviral therapy, but it is less common among HIV-negative patients. IRIS can manifest as a paradoxical worsening or recurring of preexisting tuberculous lesions or development of new lesions despite successful antituberculous treatment. Hence, the condition might be misdiagnosed as superimposed infections, treatment failure, or relapse of TB. This pictorial essay reviewed diagnostic criteria and various thoracic manifestations of the paradoxical form of TB-associated IRIS (TB-IRIS) that might aid in early recognition of this clinical entity among HIV-negative patients. The treatment and outcomes of TB-IRIS were also discussed.
