Midline cerebral arterio-venous anomalies: ultrasound diagnosis

摘要

Ultrasound features of three cases of midline cerebral arterio-venous anomalies of neonates presenting with congestive heart failure are presented. Two cases have CT and angiographic correlation. The third case has post-mortem correlation. Ultrasound easily detected the dilated midline vascular channels in all three cases. Angiography was needed to further define the abnormal anatomy. We suggest a role for ultrasound to screen for midline arteriovenous malformations in neonates with congestive heart failure of undetermined etiology.
