There is a well-marginated retrorectal or presacral space cystic lesion lateralized to the left measuring 45 x 40 x 35 mm. It displays a high signal on T1 (presence of mucinous material, high protein content, or associated intracystic hemorrhage), heterogeneous high signal on T2 with restricted diffusion and peripheral enhancement on postcontrast sequences. A mass effect is noted on the rectum which is displaced anteriorly and to the right.
Case Discussion
MRI features a retrorectal presacral cystic mass most consistent with a tailgut duplication cyst.
