“…[8][9][10] While typical myxomas are easier to diagnose, some may have atypical features that make the diagnosis challenging. [11][12][13][14] A possible cause of secondary tumors in the right atrium can be the extension of an intraabdominal tumor, like a hepatocellular carcinoma or renal cell carcinoma with a direct invasion of the inferior vena cava and the right atrium. 4,15 Even though data regarding right atrial thrombosis are scarce, a review from Sweden reported a prevalence of right atrium thrombi of 7% in 23,796 autopsies.…”

Introduction Cardiac masses are at the attention of health specialists since the development of echocardiography. Even though imaging is an excellent tool for diagnosis, the clinical presentation, risk factors, and hemodynamic status of the patients are important in establishing the diagnosis and subsequent management. The purpose of this presentation is to assess the difficulty of diagnosis in the case of an intracardiac mass and its therapeutic management. Case report A 29-year-old female with paresthesia in the left arm and a systolic tricuspid murmur underwent echocardiography, which revealed a mass of 35/20 mm in the right atrium. Due to the high embolic risk, the patient was referred to the cardiac surgery department and underwent surgical removal of the cardiac mass, which presented the macroscopical aspect of a myxoma. However, the histopathological examination revealed a right atrial thrombus. Conclusion Right heart thrombi represent a challenging diagnosis that involves a multidisciplinary team for the diagnosis and treatment of the patient.

“…Large myxomas typically remain clinically silent until they reach a significant size, or they simply cause non-specific symptoms such as fatigue and palpitations. However, giant myxoma in the right heart cavity is a rare clinical presentation (3,4).Clinically significant embolic events are much less common in patients with right atrial myxoma compared to those with left atrial myxoma (5). Additionally, myxomas may lead to syncope and sudden death due to tricuspid valve obstruction (6).…”

Primary heart tumours are rarely encountered. Myxomas, which are included in this group of tumours, are the most common primary benign neoplasms of the heart and approximately 75-80% of them are found in the left atrium. In our case, a 72-year-old female patient, who had complaints of shortness of breath, pain in the chest and swelling in the legs that increased in the last three months. We present a case with a myxoma in the right atrium with a dimension of 80x60x15 mm attached to the interatrial septum. According to the echocardiographic examination, it clinically shows signs of right heart failure, almost completely obstructs the right atrium and extends to the right ventricle. Ascending aortic aneurysm was also detected on the echocardiography. Despite the fact that the right atrial mass obliterating the cardiac chambers was removed by surgery, the valve pathology caused by the lesion did not regress.
