Introduction: Atrial myxomas are the most common primary heart tumors. Because of nonspecific symptoms, early diagnosis may be a challenge [1] [2]. Left atrial myxoma may or may not produce characteristic findings on auscultation. Two-dimensional echocardiography is the diagnostic procedure of choice. Most atrial myxomas are benign and can be removed by surgical resection. Cardiac myxoma is located mostly in left atrium [3]. This was amazing huge mass of cardiac myxoma in unusual part of the heart with the patient showed significant response to anticoagulation after presumed recurrence of tumor. Case Presentation: A case of giant right atrial myxoma mimicking the right ventricular tumor is described. Surgery was performed in 41 years old female and the fist like tumor with its stalk was excised. Surprisingly it recurred after 2 month as the smaller tumor was completely resolved with anticoagulation therapy. In addition because of previous normal echocardiography that was done for another reasons, we estimated the speed of tumor’s growth (3 millimeter/month). Conclusion: To sum up a very large myxoma in right ventricle may only present with occasional dyspnea and we can diagnose it with precise evaluation and with performing on time echocardiography.
