Esophageal cyst is a rare congenital cystic disease that usually occurs in the posterior mediastinum. Recently we experienced a case of esophageal cyst which was removed under thoracoscopic surgery. A 36-year-old man was admitted to our hospital because of an abnormal electrocardiogram, and pointed out an abnormal shadow on his chest roentgenogram. Chest CT showed a 4.8×3.2cm oval-shaped tumor in the left posterior mediastinum. Magnetic resonance imaging of the chest revealed that the tumor had iso signal intensity on T1-weighted image and had low to iso signal intensity on T2-weighted image. We surgically removed the tumor with suspicion of neurogenic tumor. The tumor was 6.0×4.0×3.5cm in size with smooth surface. The tumor had 0.5-2.0mm thick wall and structure of unilocular cyst. The content of the tumor was brown dreg-like. Pathologically, the tumor was diagnosed as an esophageal cyst lined by squamous epithelium ovelying double smooth muscle layers.
