Neovascularity of Pulmonary Hypertension
Imaging findings
CT chest shows severe pulmonary arterial hypertension with marked main pulmonary artery dilation, right ventricular hypertrophy, and right atrial enlargement. Widespread mosaic attenuation and multiple subsegmental centrilobular ground-glass nodules are present, associated with highly tortuous, corkscrew-like peripheral pulmonary arterioles.
Key takeaways
Long-standing, severe pulmonary arterial hypertension can cause neovascularity of the lung parenchyma. This manifests as highly tortuous, corkscrew peripheral vessels and centrilobular ground-glass nodules, representing muscular artery hypertrophy and capillary congestion. These lesions can bleed, causing hemoptysis.
