A Multi-organ Abscesses Including Brain Caused by a Congenital Pulmonary Arteriovenous Fistula

In cases of brain or other organ abscess, the causative etiology or disease are not always definable. We report a case of brain, renal, and possibly lung abscesses in a middle aged woman. After close, stepwise surveillance of possible etiologic factors, we covered out a small solitary pulmonary arteriovenous fistula without any pulmonary symptoms and successfully occluded the fistula via endovascular approach. The congenital pulmonary arteriovenous fistula should be bear in mind as a cause of repeated, multiple systemic infective source spray and be pursued despite of negative initial baseline studies.
