A large cyst without any solid or abnormal enhancing component was seen behind the rectum in presacral space. Its diameters are 58×44×61 mm, and its attenuation valves measured 7HU.
A 30 mm intramural mass was noted in the uterine body inferring fibroid.
Case Discussion
Retrorectal unilocular non-enhanced cystic lesion is most likely compatible with tailgut duplication cyst.
