Case report
A 51-year-old woman presented with pelvic pain, constipation, and fecal
urgency complaints. She had no past medical history or any familial
history.
In rectal examination she had a palpable rectal mass in distal part with
mild tenderness in touching. The rectal lumen was intact with flat
mucosa on colonoscopy, but posteriorly, the rectum seemed under external
pressure.
The abdominopelvic computed tomography(CT) scan revealed a hypodense
cystic lesion measuring 99*93 mm in the left retro-rectal region without
contrast enhancement, causing a rectal deviation to the right side.
