Background : Primary cardiac schwannoma is extremely rare; only 17 cases have been reported in the literature. Primary schwannoma is believed to originate from the cardiac plexus or the cardiac branch of the vagus nerve, and thus, most reported cardiac schwannomas have involved the right side heart, but left-side schwannomas have also been reported. We would report a case of cardiac schwannoma.
Methods : . A 42-year-old woman was transferred from a clinic because of cardiomegaly as determined by chest X-ray. A transthoracic echocardiography and chest computed tomography examination revealed a huge mass in the pericardium compressing the right atrium, superior vena cava (SVC), left atrium, and superior pulmonary vein. To confirm that the tumor originated from either heart or mediastinum, cine magnetic resonance imaging was performed, but the result was not conclusive.
Results : At surgery, a huge tumor in the interatrial septum was confirmed. By incision on the atrial roof between the aorta and SVC, tumor enucleation was performed successfully under CPB.
The tumor did not infiltrate into right or left atrium, and thus, interatrial septal wall repair was unnecessary. Grossly, the mass was 14 X 10 X 7 cm sized, weighed 370 g, and was lobulated, encapsulated, yellowish, and contained a hemorrhagic region. Microscopic findings revealed the presence of Antoni A and B bodies and positive immunohistochemistry for S-100 protein. These findings were compatible with benign schwannoma.
Conclusion : In the present case, the base of mass was in the interatrial septum, but it did not infiltrate into the right or left atrial cavity. We believe this is the first case of schwannoma in the interatrial septum removed by enucleation alone.
