Number 08-08 Incidental chest findings – is CT needed?
Case from: Caroline Coats, Derek Hausenloy, Maite Tome, James Moon. Department of Cardiology, The Heart Hospital, London, UK
Interpretation: No CT is needed. This is an azygous lobe, a normal variant and no further imaging is needed. The azygous lobe is a small accessory lobe above the hilum of the right lung, formed in fetal life when the azygous vein fails to migrate over the apex of the lung. It occurs in 1% of people and requires no specific treatment.
