CTICasesRecurrent pulmonary capillary hemangiomatosis
Imaging findings
Serial chest CT scans over 13 years show progressive, diffuse interstitial/septal thickening and crazy-paving in a native lung, followed by the development of similar ground-glass nodules and septal thickening in a transplanted lung. Histopathology of both lungs confirmed pulmonary capillary hemangiomatosis.
Key takeaways
Pulmonary capillary hemangiomatosis is a rare cause of post-capillary pulmonary hypertension. While treated with lung transplantation, it has a high propensity to recur in the transplanted lung, behaving pathologically like a low-grade neoplastic process.
