In this report, we describe a case of multiple brain abscesses associated with diffuse congenital pulmonary arteriovenous malformations (PAVM). Although the cases of brain abscesses associated with congenital PAVM are very rare, the brain abscess could be an initial clinical manifestation in asymptomatic PAVM as in the case presented in this report. PAVM may contribute to the development of a b...

The complete or partial spontaneous disappearance of a cerebral arteriovenous malformation is rare. Spontaneous thrombosis in large arteriovenous malformations has been reported in only two cases. We report the case of a large arteriovenous malformation in a 17-year-old man, that thrombosed spontaneously after minor surgical manipulation and review the literature and some possible mechanisms fo...

Vein of Galen abnormality is a rare congenital malformation of blood vessels of the brain and while often referred to as "Vein of Galen aneurysm" its is really not an aneurysm but usually an arteriovenous (AV) malformation. The following case report will be of interest to sonographers as it demonstrates early prenatal diagnosis of this intracranial vascular abnormality causing cardiac overload ...

Copyright © 2007 Massachusetts Medical Society. A 51-year-old woman presents with a generalized tonic–clonic seizure. After a brief postictal period, she recovers fully and does not report headache or other neurologic symptoms. She takes no medications and her medical history is unremarkable. Computed tomography of the head suggests a right occipital arteriovenous malformation, without evidence...

Multifocal capillary malformation (CM) is the cardinal feature of patients with RASA1 mutations. These CMs are 'red flags', signalling the possible association with an arteriovenous malformation (AVM) or an arteriovenous fistula (AVF). We report an 8-year-old boy who presented with > 20 CMs, who was found to have a novel mutation in the RASA1 gene. Radiological screening of children with RASA1 ...
