A chest X-ray showed a homogeneous soft tissue mass 20x30mm at the left upper lobe of the left lung (Figure 1).
Three-dimensional computed tomography angiography revealed a 35-mm vascular malformation within the perihilar left upper lobe with a single feeding artery originating from the pulmonary artery and a single draining vein.

A computed tomography (CT) pulmonary angiogram showed a 35-mm arteriovenous malformation (AVM) within the patient's perihilar left upper lobe and a small AVM within the apical segment of the right lobe (Figure 2).

On the right apical segment were two feeding arteries (Figures 3, 4). The control angiogram was performed with the same diagnostic catheter (Figures 3, 4).
