The most common chest radiography finding in pulmonary veno-occlusive disease (PVOD) is the presence of interstitial infiltrates. Kerley B lines similar to those associated with pulmonary edema may be seen as a result of interstitial edema and enlargement of pulmonary lymphatic channels. Central pulmonary arteries may be enlarged, as in other causes of pulmonary hypertension, and scattered, patchy opacities may be present. Pleural effusion may be present and is mostly right sided. However, the absence of these radiographic abnormalities does not exclude the condition. [39]
