It is thought to typically affect children and young adults Clinical presentation The clinical presentation overlaps that of primary pulmonary hypertension. Pathology Pathologically, PCH is characterized by proliferation of benign thin-walled capillary-sized blood vessels within the lung parenchyma 5.
Proliferating capillaries invade the pulmonary interstitium and alveolar septae and occlude the pulmonary vasculature. Invasion of pulmonary veins and, less frequently, pulmonary arteries can be common 8. Radiographic features CT The typical radiographic appearance described is that of a diffuse bilateral reticulonodular pattern associated with enlarged central pulmonary arteries 3.
This pattern is often mixed with lobular ground-glass opacities 6. The left atrium is normal or small in outline 6. Treatment and prognosis The natural history of pulmonary capillary haemangiomatosis is one of rapid deterioration 3. PCH has not been reported to recur after transplantation.
There are occasional reports of successful antiangiogenic therapy with Doxycycline History and etymology It was first described by Wagenvoort et al.

To the Editor: We read with interest the recent publications in the Brazilian Journal of Pulmonology highlighting the prevalence of pulmonary hypertension PH in Brazil, particularly as a complication of sickle cell anemia 1 and schistosomiasis, 2 and discussing the role of imaging methods in the evaluation of this disease. A year-old male nonsmoker presented to the pulmonology department with a three-month history of rapidly progressive dyspnea.
