Brain Abscess Due To Asian Nocardia in a 63 Years-Old Patient with Adult Still´S Disease: A Rare Case Report and Literature Review

Cerebral nocardiosis is a rare and opportunistic pathology caused by a gram-positive, aerobic bacterium of the order of Actinomycetes called Nocardia spp. It appears in patients with immunodeficiencies affecting cellular immunity. Nocardia can affect an organ (lungs in 75% of cases) or manifest itself as a disseminated infection (central nervous system in 25% of cases). Here we present a rare case of 63-years-old patient immunocompromised by monoclonal biologic treatment for Adult-Onset Still disease (AOSD), who subsequently presents fever, signs of motor focality and resonance imaging findings which show supra and infratentorial lesions. The patient is managed in intensive therapy for sensory impairment, receiving standardized antibiotic scheme, getting through to complicated evolution. Cerebral nocardiosis is a rare infectious disease that requires an early diagnostic study and its respective treatment.
