title: Neisseria elongata endocarditis complicated by brain embolism and abscess.
abstract: We report a case of Neisseria elongata endocarditis with thalamic septic embolization and subsequent brain abscess formation, which to the best of our knowledge has never been reported in the literature. The brain abscess completely resolved after a surgical repair of the infected mitral valve and an additional 4 weeks of antimicrobial therapy. Based on a review of all previous reports of N. elongata endocarditis, including ours, this will remind physicians that invasive N. elongata infections should be managed and followed up cautiously, as surgical intervention is often required.
