CTPA Pulmonary Embolus 15 Years Later Obstructive Dystrophic Calcification
CTPA 15 years following an acute pulmonary embolus reveals an obstructive dystrophic calcification at the origin of the middle lobe pulmonary artery (b ringed in white).  There is a suggestion of paucity of contrast in the middle love

Pulmonary Embolus 15 Years Later
Obstructive Dystrophic Calcification
Attenuated Middle Lobe Artery

CTPA Pulmonary Embolus 15 Years Later Obstructive Dystrophic Calcification Attenuated Middle Lobe Artery
CTPA 15 years following an acute pulmonary embolus, reveals an obstructive dystrophic calcification at the origin of the middle lobe pulmonary artery (a, green arrowhead) The middle lobe arteries distal to the calcification are attenuated due to proximal obstruction (a, red arrowhead and b red ring) . The normal sized arteries are shown in images ringed in images c, d and e demonstrating the normal ratio of arterial to bronchiole size. There is only mild scarring and ground glass change in the middle despite the apparent decrease in size of the artery.
