Imaging findings
CT chest shows modest dilation of the main pulmonary artery with extensive, smooth, layering calcification along the intima of the main and branch pulmonary arteries. Layering, non-occlusive in situ thrombi are present, with no distal occlusions.
Key takeaways
Pulmonary artery calcification is a rare sign of severe, long-standing pulmonary hypertension (typically Group 1 PAH or uncorrected congenital shunts). It reflects atherosclerotic change in the high-pressure pulmonary arterial tree. This high-pressure state also predisposes to in situ thrombus formation.
