[Multiple brain abscesses associated with Rendu-Osler-Weber disease: report of two cases]

Two cases of multiple brain abscesses associated with congenital pulmonary arteriovenous fistula are reported. A 57-year-old male with Rendu-Osler-Weber disease complicated by pulmonary arteriovenous fistula developed multiple brain abscesses in the right parietal region. He responded well to surgical drainage and antibiotic therapy, and the pulmonary arteriovenous fistula, located in the left lower lobe, was resected. A 26-year-old female with Rendu-Osler-Weber disease complicated by pulmonary arterivenous fistula developed recurrent multiple brain abscesses in both the frontal and right parietal regions. The brain abscesses were successfully treated with aspiration and antibiotic therapy. She had a history of two previous brain abscesses in the right parietal regions that were excised on separate occasions at 16 and 23 years of age. Although pulmonary arteriovenous fistula was confirmed by angiography, in this case surgical removal of the pulmonary lesions was not indicated due to multiple vascular shunting. The patient had no recurrence of brain abscess with oral antibiotic therapy.
