Cystic tumor of the atrioventricular nodal region.
We report a case of a 66-year-old female who presented exertional dyspnea and palpitation. Echocardiography, transesophageal echocardiography and computed tomography showed a right atrial cystic mass attached to the interatrial septum. The patient underwent successful excision of the mass. The histopathological findings confirmed the lesion as a cystic tumor of the atrioventricular nodal region. This is the third known case of this condition diagnosed antemortem and treated successfully with surgical excision.
