Systemic lupus erythematosus (SLE) is a multisystem inflammatory disease, in which infection is responsible for high rates of mortality. The use of corticosteroids and immunosuppressive therapy contributes to this high incidence of infections. Although bacteria are the most common agents, a wide variety of pathogens has been reported. This article reports a case of SLE in a 15 years-old boy with disseminated criptococosis (central nervous system, lungs and kidneys) and presumptive tuberculous encephalitis. The coexistence of infection by Cryptococcus and SLE is described in the literature, but the combination of this with tuberculous encephalitis is uncommon. The potential risk of infection in immunosuppressed SLE patients should alert the physician to adopt early diagnostic and therapeutic strategies aiming at an extended spectrum of pathogens.
