Pulmonary Vein Varicosity
Epidemiology
- Very rare (<100 reported cases)
Physiology
- Congenital or acquired pulmonary venous tortuosity/dilatation near entrance to LA
Diagnosis
- CXR/Chest CT Pattern: round or oval slightly lobulated, well-defined nodule (1-3 cm)/ may be multiple
- Location: medial third of lung (lingular vein on left or medial basal vein on right), close to LA
- Calcification: none
- Cavitation: none
- Change in size with Valsalva/ Mueller maneuvers
- Pulmonary angiogram: late filling and slow drainage (as compared to pulmonary AVM)
