title: Late diagnosis of odontogenic sinusitis with near-fatal outcome - a case report.
abstract: Subdural empyema is a rare but potentially life-threatening complication to sinusitis. Awareness of infection and early diagnosis is of the essence when dealing with a putatively immunosuppressed patient. Furthermore, patients at increased risk of infections due to immunosuppression need to be fully informed of risks associated with their treatment.
