🎯 Mass in the hilum that contacts hilar vessels will obscure them, similar to the silhouette sign.
🎯 Hilum overlay sign: mass anterior or posterior to the hilum does not touch the vessels so they remain visible through it.

🎯 CTCA: Enlarged right atrium and ventricle with a wide secundum ASD. Coronaries show multifocal calcification and the aortic root is dilated.
🎯 Secundum ASD is the commonest interatrial septal defect, located at the fossa ovalis.

Shutting down the government is a big deal. People have been hurt in big ways as a result of the decision. To have that suffering be for nothing—to re-open the government without actually having protected people’s health insurance and economic well-being—is unconscionable.
