Case Report: Basal ganglia brain abscess caused by Nocardia farcinica.

We report a rare case of Nocardia farcinica brain abscess in the basal ganglia, detailing its diagnosis, management, and rehabilitation. Diagnosing brain abscess based solely on clinical and imaging findings remains extremely challenging. Fortunately, metagenomic next-generation sequencing (mNGS) proved valuable in this case by rapidly identifying the pathogen, thereby facilitating targeted antibiotic therapy. This case highlights the importance of differentiating brain abscess from ischemic stroke and intracranial tumors. After completing a full course of anti-infective therapy and comprehensive rehabilitation, the patient achieved significant recovery in activities of daily living (ADL).
