Abstract
Pulmonary arteriovenous (AV) malformations occur sporadically and in the pediatric population are most commonly associated with hereditary hemorrhagic telangiectasia. Hemoptysis is an infrequent presentation in this age group. Pulmonary angiography is considered to be the definitive diagnostic modality. The authors describe an otherwise healthy eleven-year-old girl who presented with massive hemoptysis secondary to a large bronchial AV malformation unrelated to any congenital anomalies. The pulmonary angiogram appeared normal and the diagnosis was established by digital subtraction aortography. Successful embolotherapy was performed by selective injection of polyvinyl alcohol particles into the culprit bronchial artery.
