Cardiac angiofibroma is a very rare diagnosis when a patient develops an intracardiac mass. It is a primary benign cardiac tumor with a scarcity of information in the literature. This case report illustrates a 26-year-old man with a complaint of chronic chest tightness who was first diagnosed with right ventricle tumor by echocardiography then underwent cardiac magnetic resonance imaging (CMR) which confirmed the presence of a highly-vascular tumor with radiologically benign behavior. Then his tumor was excised, his postoperative course was uncomplicated and he was well within almost 2 months after discharge. Ultimately the histopathologic findings demonstrated vascular and stromal tissue in favor of angiofibroma and excluded the other diagnoses with immunohistochemical and trichrome staining. Angiofibroma is a benign, highly vascular tumor, mostly discovered in the nasopharynx. When it is found in the heart, CMR and pathology are pivotal to rule in its diagnosis. It is isointense in T1 weighted and hyperintense in T2 weighted sequences with intense enhancement following contrast injection. Its pathology contains an admixture of vasculatures with CD31 positive immunoreactivity for endothelial cells and fibrotic tissue with bluish coloration in trichrome staining. Eventually, its treatment includes merely surgical excision given its benign nature.
