Background: Pulmonary arteriovenous malformations (PAVMs) are direct connections between an artery and a vein in the pulmonary circulation associated with hereditary hemorrhagic telangiectasia in up to 88% of cases. Patients with PAVMs are at increased risk of brain abscess ( BA). This study aimed to provide preliminary data on the prevalence of PAVMs among BA patients. Methods: Administrative hospital discharge forms were used to identify patients with BA; possible PAVM patients were screened. Results: 126 patients with BA were identified. Two patients had undiagnosed PAVMs at the time of admission for BA. The age-adjusted incidence of BA was 6.3 cases/1 million/year, with a male: female ratio of 2.0. Conclusion: Although PAVMs are rare conditions, they play a role in the development of BA. PAVMs are usually not recognized at the time of BA, thus exposing patients to life-threatening risks.
