Fig. 1A —34-year-old woman with suspected intestinal implants of
endometriosis. Lateral (A) and oblique (B) spot images show
three endometriotic lesions exhibiting extrinsic mass effect with crenulation
of contour and spiculation that are direct signs of infiltration of bowel wall
(arrows). Small polypoid lesion (arrowhead) is benign
tubular adenoma confirmed at surgery.

Fig. 2 —28-year-old woman with suspected intestinal implants of
endometriosis and finding of rectal localization of intestinal endometriosis.
Double-contrast barium enema image shows extrinsic mass effect and spiculation
(arrow) of rectal wall that appears infiltrated. Surgical and
histologic findings confirmed intestinal implants of endometriosis.

Fig. 3 —23-year-old woman with suspected intestinal implants of
endometriosis. Double-contrast barium enema examination showed pathologic
pelvic process involving bowel serosa at rectosigmoid junction. Finding of
extrinsic mass effect and spiculation (arrows) owing to poor wall
distention after air insufflation suggested endometriotic wall infiltration.
Histologic examination of these alterations showed adnexal inflammation
originating from ovary.

Fig. 4A —31-year-old woman with suspected intestinal implants of
endometriosis and finding of cecal localization of intestinal endometriosis.
Double-contrast barium enema image of cecum shows endometriotic localization
as endoluminal filling defect (arrow) due to wide extrinsic mass
effect confirmed at surgery.

Fig. 4B —31-year-old woman with suspected intestinal implants of
endometriosis and finding of cecal localization of intestinal endometriosis.
Photograph of surgical specimen shows endometrial glands and stroma
infiltrating fibromuscular tissue, smooth-muscle proliferation, and fibrous
reaction, resulting in thickening of wall with endometriosis. Multiple cysts
(arrow) are present in perivisceral fat tissue. Mucosal sparing is
typical of this disease.
