title: An unusual presentation of subdural empyema caused by Porphyromonas gingivalis.
abstract: Subdural empyema is an uncommon clinical entity. The first case of Porphyromonas gingivalis subdural empyema is reported. We report a case of 34-year-old male who presented with subdural empyema and sinusitis. Through the utilization of polymerase chain reaction (PCR) tests on subdural pus, we were able to confirm the diagnosis and institute appropriate treatment. Early surgical intervention and intravenous antibiotics meant that the patient recovered fully. Infections caused by P. gingivalis should be considered in differential diagnoses of central nervous system (CNS) abscesses or subdural empyema especially in patients with precedent periodontal diseases and sinusitis.
