Nonobstructive dilatation of one or more pulmonary veins at insertion into left atrium (LA)
May be isolated radiologic finding
May be congenital or associated with acquired heart disease (e.g., mitral stenosis ± regurgitation)
No enlarged feeding artery or arteriovenous communication
May be mistaken for mediastinal, hilar, or pulmonary mass
