title: A case of an immunocompetent young man obtaining community-acquired disseminated Nocardia brasiliensis.
abstract: Nocardiosis is a rare but severe pyogenic or granulomatous disease and caused by Nocardia that mainly infects immunocompromised patients. We report here a case of an immunocompetent 24-year-old male student with community-acquired pneumonia with asymptomatic disseminated cerebral abscess by Brasiliensis nocardiosis. The patient was fully recovered after receiving optimized antimicrobial therapy without relapse. This case suggests the health professionals such as the physicians of pulmonary, infection, neurology department and et al should always think about unusual cause of community acquired pneumonia, even in immunocompetent patients and when having pulmonary nocardiosis we should do a radiological neurological work up, even with the absence of neurological finding or symptom.
