Despite their rarity, they can mimic conditions like a right atrial thrombus, complicating the diagnosis. This case report presents the diagnostic journey of a right atrial myxoma in a 54-year-old female patient, focusing on the importance of differentiating it from a thrombus. The report includes detailed diagnostic workup and emphasizes the role of advanced imaging modalities and histopathological examination.EnglishRight atrial myxoma, Cardiac tumor, Right atrial thrombushttps://www.yemenjmed.com/admin/abstract?id=135References16191.
