Purpose:
To describe the CT findings of pulmonary veno-occlusive disease.
Materials And Methods:
Pre-therapeutic CT of 15 patients suffering from pulmonary veno-occlusive disease were retrospectively reviewed. Pathologic evaluation of pulmonary veno-occlusive disease was obtained after post mortem examination or pulmonary transplantation. CT protocol always included intravenous helical CT and high resolution CT.
Results:
The most frequent CT-findings in pulmonary veno-occlusive disease were the following: ground glass opacity with poorly defined nodular opacities (73%), septal lines (93%), and adenopathy (80%). Pericardial (60%) and pleural effusions (27%) were also noted. Other parenchymal findings were unusual.
Conclusion:
HRCT must be systematically included in the initial CT evaluation of pulmonary hypertension. Combination of poorly defined nodular opacities, septal lines, and adenopathy are indicative of pulmonary veno-occlusive disease.
