Abstract

Background: Brain abscesses caused by Nocardia are rarely reported and have high mortality. It usually affects patients who are immunocompromised and initiates as a lung infection that disseminates hematogenously, though it can also affect those immunocompetent. Cerebral nocardiosis imitates brain tumors, which can delay the initiation of the appropriate antibiotic therapy.

Case Description: We present a case of a 64-year-old immunocompetent male with multiple cerebral abscesses who presented with headaches, left-sided weakness, and ataxia. Upon imaging, multiple brain lesions were revealed. The patient underwent craniotomy and drainage of the mass. He was initially empirically treated, though cultures later grew Nocardia Asteroides. He was initially treated with Meropenem and Bactrim and was discharged on Bactrim alone once the sensitivities came back resistant to meropenem. The patient was discharged on Bactrim alone to complete 12 months of treatment. He had a full recovery one-month post-surgical and antimicrobial intervention.

Conclusions: Due to the high mortality rates associated with Nocardia brain abscesses, clinical suspicion should always be high for Nocardia. Early surgical intervention and species identification are paramount to initiating long-term antibiotic therapy. In our experience, a successful outcome was achieved with total resection and prolonged and adequate antibiotic therapy.
