Esophageal leiomyoma in a 35-year-old woman.

A. Chest radiograph shows a right retrocardiac soft-tissue mass (arrows), with obliteration of the azygoesophageal recess interface.

B. Enhanced (10-mm collimation) CT scan obtained at the ventricular level depicts a 60-mm-sized, slightly inhomogeneous, iso-attenuated, pear-shaped mass (arrows) in the right azygoesophageal recess.

C. T2-weighted MR image obtained at a similar level to B shows that compared to chest wall muscle, the mass is isointense (arrows).
