Findings:

serpentine intraluminal foreign bodies = ascaris worms

thin ribbon of contrast = barium WITHIN worm GI tract

surrounding abnormal posterior mucosa

ddx:

due to increased acidity in the duodenal bulb

ddx:

Hyperplastic polyps

Familial polyposis syndromes

11.

do NOT penetrate beyond the muscularis mucosa

ddx:

Crohn’s disease

Inflammatory polyps

Findings:

islands of normal or edematous mucosa seen during active inflammation

they protrude into the lumen because the surrounding mucosa is sloughed or deeply ulcerated

numerous, slightly elevated lesions measuring a few millimeters clustered in a small segment of the duodenal bulb

may have angulated or plaque-like margins

occur in up to 20% of pts.

no clinical significance

ddx:

benign lymphoid hyperplasia (if 1-2mm smooth filling defects)
