Few faint ground-glass patches are seen at the right upper and middle lobes, suggestive of pulmonary infection.
Lobular lingular homogeneous density is noted with smooth wall and no calcifications that is connected to two prominent vascular channels, one is draining to the left atrium through the left superior pulmonary veins representing the draining vein and the other is connected to the left pulmonary artery at the left hilum representing the feeding pulmonary artery. Features are in keeping with pulmonary arteriovenous malformation.
