Background and purpose: 

Disseminated Mycobacterium avium complex (MAC) infection involves the central nervous system (CNS) less frequently than tuberculosis, and MAC-related immune reconstitution inflammatory syndrome (IRIS) of the CNS in AIDS patients is even more rarely described. We report a case of MAC-related IRIS of the CNS in an HIV-infected patient who presented with meningoencephalitis and myelitis 2 months after discontinuation of antiMAC therapy, when he had achieved prolonged suppression of HIV replication and restoration of CD4 counts to >100 cells/μL for 1 year. Cases of MAC-related IRIS of the CNS reported in the literature are reviewed.



 

Key words:

HIV, Immune reconstitution inflammatory syndrome, Meningoencephalitis myelitis, Mycobacterium avium complex
