The "ring-around-the-artery" sign in pneumomediastinum. 1984

D I Hammond

Following subclavian vein catheterization, a small pneumomediastinum resulted in the collection of a thin layer of gas around the right pulmonary artery (RPA), which, on the lateral chest radiography, produced a distinctive oval shadow at the right hilum.
