Abstract

Two-dimensional echocardiography is a simple, noninvasive method of evaluating cardiac strucures and pericardiac structures. The diagnosis of pericarial cyst is strongly suggested by the prominent roentgenographic appearance of a round, sharply demarcated mass along the right cardiac silhouette in an asymptomatic patient. Two-dimensional echocardiography is also useful method for diagnosing pericardial cyst, but differential diagnosis is difficult when other mass revealed echo-lucent cystic nature is located adjacent to the right atrial wall. We report the similar two-dimensional echcardiography findings located adjacent to the right atrial wall which are diagnosed different disease entity each oter. We suggest that two-dimensional echocardiography helps diagnosis of mass adjacent to the right atrial wall and may need more extensive investigation for accurate differential diagnosis.
