Myxoma , which is the most common primary tumor of the heart, is commonly located in the left atrium. Although intra cardiac myxomas are histologically benign, they may be the source of cerebrovascular emboli, cause of mitral stenosis and nonspecific systemic complaints like fever and arthralgia. A 55-year-old woman was followed by rheumatology clinic because of subfebrile fever and arthralgia for 6 months. She admitted to our clinic with complaint of dyspnea and orthopnea.Transthoracic echocardiography showed giant myxoma in the left atrium. Transmitral pressure half time (PHT) was assessed by continuous wave doppler and measured maximum/mean 29/17 mmHg transmitral gradient. Mitral valvular area was measured 1,6 cm2 by PHT. We demonstrated a mass like myxoma, which originates from interatrial septum and caused functional mitral valve stenosis, size of 55x31 mm by transesophageal echocardiogram. Surgery was performed and the intracardiac mass was removed. Pathological examination demonstrated myxoma. We report a patient of a huge left atrial myxoma with functional mitral valve stenosis and complaints of subfebrile fever and arthralgia. 2 months after the operation the patient's subfebrile fever disappeared and complaints of arthralgia decreased. The complaints completely disappeared and sedimentation rate was normal after 4 months. Subfebrile fever and arthralgia was suggested to be secondary to myxoma.
