Fig. 2. —40-year-old man with abdominal pain. Spot image from upper

central collection of barium (solid arrow). Central collection was
found to be depression rather than ulcer. Pylorus is marked by open arrow.

Fig. 3. —45-year-old woman with mass in fundus of stomach that was
identified on chest radiograph (not shown). Radiograph of fundus from upper
gastrointestinal examination shows mass with significantly decreased density
and no ulceration, findings suggestive of lipoma.

Fig. 6. —22-year-old man with no gastrointestinal symptoms. CT scan
obtained for follow-up of testicular cancer shows large 9-cm mass
(asterisk) in fundus of stomach. Some high-density areas within mass
are visible, but diffuse low density is diagnostic of lipoma.

Fig. 7A. —78-year-old woman with acute onset of gastrointestinal
bleeding. Upper gastrointestinal examination showed large 8-cm mass in antrum
with central ulceration. CT scan obtained through antrum shows low-density
mass (asterisk) containing some higher density stranding. Ulcer is
not visible. Higher density is probably due to ulceration.

Fig. 7B. —78-year-old woman with acute onset of gastrointestinal
bleeding. Upper gastrointestinal examination showed large 8-cm mass in antrum
with central ulceration. Photograph of gross pathology specimen shows typical
features of lipoma extending into lumen. Gastric mucosa is being displaced by
lipoma (arrows). Ulcer is not shown.
