Imaging findings
CT in a patient with treated Group 1 PAH shows central pulmonary artery dilatation, pleural effusions, hilar/mediastinal adenopathy, and tiny centrilobular ground-glass nodules representing plexiform arteriopathy rather than PVOD/PCH, in the setting of severe hypoalbuminemia.
Key takeaways
Tiny centrilobular ground-glass nodules in Group 1 pulmonary arterial hypertension represent plexiform lesions (arteriopathy). When associated with pleural effusions and adenopathy, this can raise concern for PVOD, but low oncotic pressure (hypoalbuminemia) must be excluded.
