Cover image supplied by Márton Kolossváry, Kinga Sámson, Csaba Csobay-Novák, Béla Merkely, and Pál Maurovich-Horvat from the MTA-SE Cardiovascular Imaging Research Group, Semmelweis University, Budapest, Hungary. The picture shows a volume-rendered CT image of a rare case of idiopathic retroperitoneal fibrosis (Ormond disease) with cardiac involvement. Proliferation of fibrous tissue can be seen around the proximal segments of the right coronary artery and the left anterior descending coronary artery. The alteration was named as the ‘mistletoe sign’
