Figure 15: A 15-year-old boy was an operated case of tetralogy of Fallot on follow-up. Recent echocardiography was suggestive of RA mass. (a) 4C cine, (b) 4C LGE, and (c) 4C T2W triple inversion recovery images show a mobile lobulated RA mass (orange arrow) attached to the interatrial septum. It shows mild central heterogeneous enhancement and appears hyperintense on T2W triple inversion recovery. He underwent surgical excision of the mass with histopathology suggestive of myxoma. Final diagnosis: RA myxoma. 4C: Four-chamber, LGE: Late gadolinium enhancement, RA: Right atrium, W: Weighted
