A 46-year-old man, a candidate for aortic valve replacement, was referred to us after an invasive coronary angiogram (ICA; Figure 1; Supplementary Movie 1) showed a large cardiac mass encasing the left coronary artery; there was no coronary artery stenosis.
CMR acquisition (A-E): DWI b 0 and b 1,000 (A,B) and ADC map (C) showing high cellularity of the lesion; balanced gradient echo sequence in short axis and two chambers (D,E), showing morphology and extension of a PGL. CCT acquisition (F-J): axial (F,G) and oblique planes highlighting the morphology, position, and contrast of the PGL. CR reconstructions in different planes (K-O).

CCT was performed (Figures 2F-J; Supplementary Movies 2 and 3) using a third-generation dual source CT scanner (DSCT; Somatom Force, Siemens Healthineers, Erlangen, Germany). The patient also underwent CMR imaging (Figures 2A-E) on a 1.5
