large submucosal mass with mass effect extending in to the lumen of the greater curvature of the stomach.
Gastric duplication cyst
Contrast-enhanced axial computed tomographic image at the level of the mid abdomen shows the 3 contiguous cystic lesions with thin, hyperdense linings. The cystic lesions are surrounded by hypodense tissue, which is isodense and apparently contiguous with the muscularis propria of the distal stomach.
A frontal view of the stomach from an upper gastrointestinal (GI) series demonstrates a thin, smooth-walled, saccular structure within the second and third portions of the duodenum. The majority of the contrast material is located within the saccular structure with a small amount of surrounding intraduodenal contrast material.
Dx: Intraluminal duodenal diverticulum
Duodenal wind sock sign in a patient with duodenal diverticulum. Image from an upper gastrointestinal series clearly demonstrates an intraluminal duodenal diverticulum (arrows) surrounded by a narrow radiolucent line (arrowheads). The diverticulum, arising in the second portion of the duodenum and extending to the third portion, was confirmed at surgery.
Tracheoesophageal fistula without atresia (type E). Esophagogram shows a fistula (arrow) arising from the anterior portion of the esophagus (e) and passing cephalad to the posterior portion of the trachea (t).
Esophagogram shows a tracheoesophageal fistula (arrow) located at the same level as a congenital stricture (arrowhead).
Duplication cyst in a 2-year-old girl with recurrent episodes of vomiting. Esophagogram shows extrinsic compression of the left wall of the esophagus (arrows).
Pyloric atresia in a male neonate. Frontal radiograph shows distention of the stomach and absence of gas in the small bowel (single bubble appearance).
Incomplete antral web. Radiograph from a barium study (anterior oblique view) shows a concentric radiolucent band (arrows) producing discrete antral lumen reduction. Arrowhead indicates pylorus.
Ectopic pancreas in the gastric antrum. Image from an upper gastrointestinal series shows a rounded nodular defect in the gastric antrum with central umbilication identified by a fleck of barium (arrow). The diagnosis was confirmed at surgery.
Duodenal atresia in an 8-hour-old female neonate who presented with bilious vomiting. Abdominal scout radiograph shows a markedly distended stomach and duodenum with no gas in the rest of the intestinal tract (double bubble sign).
Crohn disease. Aphthous ulcers. Double-contrast barium enema examination in Crohn colitis demonstrates numerous aphthous ulcers.
Crohn disease. Cobblestoning. Spot view of the terminal ileum from a small-bowel follow-through study demonstrates linear longitudinal and transverse ulcerations that create a cobblestone appearance. Also note the relatively greater involvement of the mesenteric side of the terminal ileum and the displacement of the involved loop away from the normal small bowel secondary to mesenteric inflammation and fibrofatty proliferation.
Crohn disease. Spot view of the terminal ileum from a small-bowel follow-through study demonstrates several narrowing and stricturing, consistent with the string sign. Also note a sinus tract originating from the medial wall of the terminal ileum and the involvement of the medial wall of the cecum.
Crohn disease of the terminal ileum with CT and sonographic correlation. Small-bowel follow-through study demonstrates the string sign in the terminal ileum. Also note pseudodiverticula of the antimesenteric wall of the terminal ileum, secondary to greater distensibility of this less-involved segment of the wall.
Crohn disease. Active small-bowel inflammation. CT scan demonstrates small-bowel wall thickening, mesenteric inflammatory stranding, and mesenteric adenopathy.
Crohn disease. Crohn colitis. Double-contrast barium enema study demonstrates marked ulceration, inflammatory changes, and narrowing of the right colon.
Crohn disease. Crohn colitis. CT scan demonstrates marked thickening of the wall of the right colon with inflammatory stranding in the adjacent mesenteric fat.
Crohn disease. Fibrofatty proliferation. CT scan in a patient with Crohn colitis in the chronic phase demonstrates wall thickening of the right colon, an absence of adjacent mesenteric inflammatory stranding, and a large amount of fatty proliferation around the right colon separating the colon from the remainder of the gut, so-called creeping fat.
Crohn disease. Enterocolic fistula. Double-contrast barium enema study demonstrates multiple fistulous tracts between the terminal ileum and the right colon adjacent to the ileocecal valve, the so-called double-tracking of the ileocecal valve.
Double-contrast spot image of stomach with patient in supine position shows moderately thickened folds in gastric body due to chronic H pylori gastritis. Folds are considerably less thickened and lobulated than in patient with Menetrier disease (Fig 29). Note surgical clips from prior vagotomy.
Double-contrast spot image of gastric body with patient in supine position shows markedly thickened, lobulated folds and diffuse distortion of areae gastricae pattern in patient with Menetrier disease.
Double-contrast spot image of gastric fundus with patient in right-side-down position shows smooth, undulating submucosal mass (arrows) on posterior wall of fundus extending to cardia. This patient had portal hypertension with a conglomerate mass of gastric varices (also known as tumorous varices). Note surgical clips from recent liver transplantation.
Double-contrast spot image of gastric fundus with patient in right-side-down position shows polypoid mass (arrows) that has obliterated and replaced normal cardiac rosette. Arrowheads denote areas of ulceration within tumor. This patient had an advanced carcinoma of cardia.
