title: Pictorial essay: Uncommon causes of coronary artery encasement.
abstract: This pictorial essay presents cases of non-atherosclerotic coronary artery encasement which were encountered in our institution, including malignant lymphoma, Erdheim-Chester disease, immunoglobulin G4 (IgG4)-related disease and Polyarteritis Nodosa. These conditions usually have multisystemic involvement which aid in the diagnosis. Awareness of these uncommon disorders and their ancillary findings can facilitate early, accurate diagnosis and appropriate management.
