Giant right atrial myxoma presented with symptoms of Budd-Chiari syndrome: a case report.

Right atrial myxoma is rarely associated with Budd-Chiari syndrome (BCS). In this paper, we present a case of a young patient with a giant right atrial myxoma complicated by the development of BCS. A 26-year-old female presented to the emergency room with persistent abdominal pain, ascites, lower limb edema, and an acute episode of dyspnea. Abdominal computed tomography revealed a lesion in the right cardiac cavity that resembled an intracardiac thrombus. Transthoracic echocardiography showed a large heterogeneous mass in the right atrium protruding into the right ventricle and a large thrombus interfering with inferior vena cava flow. The patient underwent cardiac surgery to remove the atrial mass, and histopathologic examinations confirmed the diagnosis of atrial myxoma. The right atrial myxoma is relatively rare, especially the giant ones. Rarely have intracardiac tumors such as giant right atrial myxoma been identified as a risk factor for the onset of BCS. In the differential diagnosis of BCS, right atrial tumors, including myxomas, should be considered, especially when other explanations are absent.
