Immune reconstitution inflammatory syndrome producing atypical presentations of cryptococcal meningitis: Case report and a review of immune reconstitution-associated cryptococcal infections

Atypical presentations of cryptococcal infection have been described as manifestations of immune reconstitution in HIV-infected patients following introduction of antiretroviral therapy. We describe a patient presenting with cryptococcal meningitis as an immune reconstitution reaction 10 weeks after initiation of anti-retroviral therapy. Subclinical CSF cryptococcal infection was demonstrated and the serum cryptococcal antigen was negative.
