Computed tomography of the chest demonstrating a large pulmonary arteriovenous malformation (a) and multiple hepatic arteriovenous malformations (b). Contrast-enhanced computed tomographic scans show (a) a dilated vessel in the right midperipheral lung region creating a pool of contrast, as well as a large draining vein into the right pulmonary vein suggestive of an arteriovenous malformation, and also show (b) multiple intrahepatic tortuous vessels enhancing on arterial phase suggestive of intrahepatic arteriovenous malformations and peripheral smaller ones with early venous phase displaying early filling of the hepatic veins. The splenic hilum also shows tortuous vessels suggestive of splenic hilar arteriovenous malformations
