A 50-year-old woman was admitted to our hospital for a close examination of a pericardial effusion. Five months before admission, she began experiencing episodes of exertional dyspnea and orthopnea. At the hospital she attended at that time, she was diagnosed as having a large pericardial effusion and was treated with pericardial drainage.
On admission to our hospital, her chest x-ray films showed marked cardiac enlargement. An echocardiographic examination and cardiac magnetic resonance imaging (Fig 1⇓) revealed an ovoid right atrial mass and a moderate pericardial effusion. Under cardiopulmonary bypass, the right atrial mass, measuring 9.0×5.0×6.0 cm (Fig 2A⇓), was successfully removed. The tumor surface was smooth, and its cut surface was yellow (Fig 2B⇓). Microscopic sections showed the typical Antoni type A tissue (Fig 3A⇓) and Antoni type B tissue (Fig 3B⇓). The tumor was interpreted as a cardiac neurilemoma. Primary cardiac tumor is very rare; to the best of our knowledge, only four cases have been reported in the literature.
