Immune Reconstitution Inflammatory Syndrome (IRIS) refers to a collection of inflammatorydisorders, predominantly related to infectious processes that manifest after the initiation ofantiretroviral therapy (ART) and can be classified as unmasking or paradoxical. The prevalenceof IRIS in children in sub-Saharan Africa is low. Approximately half of all cases are associatedwith Mycobacterium tuberculosis. It may be difficult to distinguish IRIS from tuberculosis andother opportunistic infections radiologically; therefore, radiological findings must be interpretedwith clinical and laboratory findings. In this review article, we describe the clinical andradiological manifestations of IRIS in children and provide illustrative radiological examples.
