Paraesophageal cystic lesion of the right posterior mediastinum (esophageal duplication cyst) in an 18-year-old woman. a–c T1-W post-contrast spoiled gradient recalled echo (SPGR) (a), T2-W axial turbo-spin echo PROPELLER (periodically rotated overlapping parallel lines with enhanced reconstruction) (b), and axial CT post-contrast (c) images. Note there is no contrast enhancement on either MRI (arrow in a) or CT (arrow in c), and the high signal intensity on T2-W imaging; these findings indicate fluid content (arrow in b)
