[Pulmonary hypertension: CT findings in pulmonary veno-occlusive disease].
OBJECTIVE
To describe the CT findings of pulmonary veno-occlusive disease.


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.


CONCLUSIONS
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.
