A year-old male nonsmoker presented to the pulmonology department with a three-month history of rapidly progressive dyspnea. Physical examination revealed digital clubbing, and he was tachypneic and cyanotic, requiring supplementary oxygen. Heart auscultation and chest examination were unremarkable, and examination of the abdomen revealed a slightly enlarged liver. A transesophageal echocardiogram showed enlargement of the main pulmonary artery and right heart chamber. Arterial blood gas analysis showed the following results: pH, 7.

A chest X-ray showed dilatation of the main and central pulmonary arteries with a nonspecific interstitial infiltrate. Chest CT angiography allowed us to exclude pulmonary embolism and revealed diffuse centrilobular ground-glass opacities GGOs and marked dilatation 36 mm of the main pulmonary artery Figure 1.

The GGOs were bilateral and symmetrical, with no thickening of the interlobular septa. Anticoagulation therapy with heparin was started and initially improved the symptoms slightly. Pulmonary catheterization demonstrated a mean pulmonary artery pressure of 65 mmHg and a negative vasoactive intestinal peptide result. The pulmonary artery occlusion pressure was 13 mmHg, and cardiac output was 2. Because of the diagnostic suspicion of PCH, the patient was placed on the waiting list for lung transplantation.

Despite the treatment with heparin and furosemide, the condition of the patient gradually deteriorated, and he died two months after admission. An autopsy revealed prominent dilation of the right heart chambers and of the pulmonary artery, as well as diffuse alveolar hemorrhage.

Microscopic examination of the lungs showed well-demarcated areas with dense proliferation of capillary channels within alveolar walls and surrounding walls of pulmonary venules and veins, which supported the diagnosis of PCH Figure 2.
