Atherosclerotic Calcification of Large Pulmonary Arteries



Figure 1. Calcification of the Pulmonary Arteries in Pulmonary Hypertension

Frontal chest radiograph shows small foci of increased attenuation involving the main and right pulmonary arteries, as well as the right interlobar and right lower lobe pulmonary arteries.

Compare with the CT below.


Figure 2. Axial Thoracic CT

This scan of the same patient confirms that the calcification is related to the walls of the pulmonary arteries. This finding, which corresponds to calcification of atherosclerotic plaques, is pathognomonic of pulmonary hypertension.
