Popis: An immunocompetent man presented withCryptococcus neoformansdisease manifesting as a large pulmonary mass (cryptococcoma). Despite an initial induction course of 4 weeks of liposomal amphotericin B (LAmB), followed by 8 weeks of fluconazole, the cryptococcoma enlarged in size. Ten days into a second course of induction therapy with LAmB and flucytosine, the cryptococcoma markedly increased in size with encroachment on critical vascular structures. Due to concern for immune reconstitution inflammatory syndrome (IRIS), prednisone was added with significant decrease in the size of the mass. To our knowledge, this is the first reported case of pulmonary cryptococcal-IRIS in an immunocompetent host.
