ABSTRACT
Pulmonary arteriovenous malformations are rare vascular anomalies. We report a 12-year-old girl who presented with exertional dyspnoea, cyanosis and clubbing since the age of five years, and multiple pulmonary arteriovenous malformations. Computed tomography pulmonary angiogram showed a large pulmonary arteriovenous malformation at the lower lobe of the right lung. Pulmonary angiogram showed a large right lung arteriovenous malformation and two small left lung arteriovenous malformations. The multiple arteriovenous malformations were occluded with Gianturco coils. She is now asymptomatic and on regular follow-up.
