Hilum convergence sign

Dr Andrew Dixon et al.

The hilum convergence sign is a useful chest radiograph sign to help distinguish a bulky hilum due to pulmonary artery dilatation from a mass/nodal enlargement. In the former, pulmonary vessels can be seen to converge and join a dilated pulmonary artery. 

History and etymology

Dr Benjamin Felson (1913-1988) was an American radiologist who first described this sign 2.
