CTICasesPulmonary Veno-Occlusive Disease (PVOD)
Imaging findings
Dilated pulmonary artery, enlarged right heart, thickened RV wall, and findings mimicking pulmonary edema (interlobular septal thickening). Notably, the left atrium is small.
Key takeaways
PVOD should be on the differential when pulmonary hypertension mimics pulmonary edema. Administering standard arterial dilators in PVOD can lead to rapid decompensation because the obstruction is in the distal venules.
