Nocardiosis is an infection caused by Nocardia species, that are filamentous aerobic Gram-positive bacilli that belong to Actinomycetaceae family, it can cause a localized or a disseminated infection. Pulmonary disease is the most common presentation of nocardiosis in immunosuppressed patients and approximately one-third have a disseminated disease, that happens when lesions are found at two or more locations in the body. Nocardial brain abscesses are a rare central nervous system infection but has been highlighted as a differential diagnosis of brain tumors, due to the increase of the infection in deficient cell-mediated immunity patients. Even though nocardiosis represents only 2% of brain abscesses, it is an illness associated with significant mortality, present on 75% to 90% of cases. We present a case of central nervous system nocardiosis in a 59-year-old patient with a previous history of diabetes mellitus and alcoholic liver disease. The patient sought the emergency department with temporal occipital headache and mental confusion for 3 days. Imaging tests were performed that showed an oval lesion in the temporoparietooccipital region. Nocardiosis in the central nervous system was hypothesized and treatment was initiated. Despite medical support, the patient died. The lesion material was collected in which nocardiosis was diagnosed when analyzed histochemically.
