Info

A large unilocular cyst without any solid or abnormal enhancing component was seen behind the rectum in the presacral space. Its diameters are 58 × 44 ×61 mm, and its mean attenuation values measured 7 HU.
A 30 mm intramural mass was noted in the uterine body inferring fibroid.
Case Discussion
Retrorectal unilocular non-enhanced cystic lesion in a patient with pelvic pain is most likely compatible with tailgut duplication cyst. Approximately 50% of patients may have perirectal symptoms, likely pelvic pain and constipation.
