case_images: a Transaxial image of FDG PET/CT showing high uptake (SUVmax 11.5) in the apex of the right ventricular. The four arrows show the same localization. b (A) Short-axis of the November 2021 thoracic CTS showing a defect in the right ventricular cavity, measured at 1.7 cm (red arrow). c (A) Short-axis view images of CMR in steady-state free precession sequence (SSFP) showing a low signal intensity at the endocavitary lesion measured at 1.7 cm (red arrow). (B) Four-chamber view images of CMR in SSFP showing the same lesion in low signal intensity measured at 1.9 cm (red arrow).

case_images: However, it revealed a localized uptake with an SUVmax of 11.5 in the right ventricle (Fig. 1). Upon reevaluation, this CM was identified in the November 2020 CT scan (Fig. 1). Trans-thoracic echocardiography was inconclusive, and cardiac magnetic resonance (CMR) imaging confirmed an intracavitary tumor measuring 19 x 13 x 3 mm at the right ventricle apex with moderate and progressive enhancement (Fig. 1).
