PULMONARY ARTERIOVENOUS MALFORMATION PRESENTNG WITH BRAIN ABSCESS: REPORT OF TWO CASES
Abstract
Brain abscess can be an initial clinical manifestation of asymptomatic pulmonary arteriovenous malformation. Recently, we were referred with two cases of brain abscess who were found to have pulmonary arteriovenous malformation, and presenting with repeated neurological symptoms; one of them had medical treatment for bacterial meningitis, and presenting again with brain abscess at 1 month after discharged, another one had repeated episodes of brain abscesses in three-years interval. Both of them had pulmonary angiographically, surgically, and pathologically proved to have arteriovenous malformation in right middle lobe and right lower lobe of lungs. The clinical findings of hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu Syndrome) were discussed.
The possible association between repeated episodes of brain abscesses and pulmonary arteriovenous malformation should be bone in mind, especially in cases with the clinical findings of hereditary haemorrhagic telangiectasia.
