title: Porphyromonas gingivalis causing brain abscess in patient with recurrent periodontitis.
abstract: We report an extremely rare case of Porphyromonas gingivalis causing brain abscess in a patient with recurrent periodontitis. The patient presented with right-sided homonymous hemianopsia and right hemiparesis. Emergent surgical drainage was performed and antibiotics were administered. P. gingivalis was identified from the anaerobic culture of the abscess. The clinical course of the patient improved with full recovery of the neurologic deficit.
