Atypical size and location of a right atrial myxoma: a case report

INTRODUCTION: Primary intracardiac tumors are rare and approximately 50% are myxomas. The majority of myxomas are located in the left atrium and have variable clinical presentation. We report a case of a large myxoma in the right atrium, which is an uncommon location for this type of tumor. CASE PRE...

Sumario:INTRODUCTION: Primary intracardiac tumors are rare and approximately 50% are myxomas. The majority of myxomas are located in the left atrium and have variable clinical presentation. We report a case of a large myxoma in the right atrium, which is an uncommon location for this type of tumor. CASE PRESENTATION: A 45-year-old Caucasian woman with a history of palpitation had dyspnea on great exertion and discrete weight loss. A cardiac evaluation showed splitting of S1. An echocardiogram showed a large mass in the right atrium, suggesting myxoma; chest computed tomography confirmed the diagnostic hypothesis. Our patient underwent surgical treatment with excision of a 10 cm multilobulated mass. She presented with supraventricular tachycardia during the operation. She was placed in the intensive care unit and her condition improved after the use of amiodarone. The diagnosis of myxoma was confirmed by histopathological study. CONCLUSIONS: In this case report, we emphasize the rarity of large myxomas in the right atrium and the difficulty of differential diagnosis given their dimension and location.
