case_images: The abdomen CT (A), abdomen MRI (B), and endoscopic ultrasonography (C and D) of
  Brunner's gland adenoma in this case. (A) Implied a uniform soft tissue
  mass shadow in the descending duodenum. (B) Revealed a significant thickening of
  the wall of the duodenal bulb and descending duodenum. (C and D) Demonstrated that
  there was a protrusion lesion with a clear boundary, smooth surface, and color
  signals in bulb duodenum.

case_images: Abdomen computed tomography (CT, Figure 1A) showed a 32 mm x 22 mm soft tissue mass shadow with homogeneous density in the descending duodenum, which was protruding into the duodenal lumen. Upper abdomen magnetic resonance imaging (MRI, Figure 1B) revealed a significant thickening of the wall of the duodenal bulb and descending duodenum. Endoscopic ultrasonography (Figure 1C and D) demonstrated that there was a protrusion in the duodenal bulb of about 26 x 18 mm in size with a clear boundary, smooth surface, and irregular shape and the base being about 17 mm, color signals abound.
case_images: The pathology of this case. It revealed multiple Brunner's glands with
  tubes, fibers, and smooth muscle diffuse distribution.
