The sigmoid lumen was opacified with rectal contrast. This demonstrates eccentric mural thickening and stenosis of the sigmoid colon (blue arrow). Mild adjacent fat stranding is noted.
Coronal section of contrast-enhanced CT (with rectal contrast) shows eccentric mural thickening (blue arrow) at the mesenteric aspect of the proximal sigmoid colon.
This image demonstrates significant narrowing of the sigmoid colon by the eccentrically located mass lesion (blue arrow). No significant proximal bowel dilation is observed.
This section demonstrates multiple small hypodense/cystic foci at the Pouch of Douglas (blue arrowheads) suggestive of endometriotic deposits.
