Abstract

Heterotopic pancreas is often an incidental finding and can be found at the stomach. However, heterotopic pancreas containing abundant fat is very rare. Fatty replacement of the pancreas is the most frequent pathologic finding, but the precise etiology of the entity remains unclear. The pathological findings observed in the pancreas can also occur in the heterotopic pancreas. Here, we present a case of heterotopic pancreas in the stomach. On CT and MR imaging, it manifested as a predominant fat-density submucosal mass with enhancing solid component.

  Fig. 1 A 44-year-old male with heterotopic pancreas in the gastric body incidentally detected on CT. A. Axial contrast-enhanced CT image reveals a well-defined fatty submucosal mass (arrowheads) in the gastric body. A more caudal scan of the CT image shows an enhancing solid component (arrow) surrounded by fat. The submucosal mass exhibits an endoluminal growth pattern. B. T2-weighted MR image shows a predominantly high-signal intensity mass (arrowheads) in the gastric body. C. Contrast-enhanced T1-weighted, fat-suppressed MR image shows a loss of signal in the fatty portions of the mass (arrow) and enhancement of the solid component (arrowhead) of the mass. D. Endoscopic image shows a submucosal mass with intact overlying mucosa in the greater curvature of the gastric body. E. Gross specimen shows a 2.8 × 2.0 × 1.5 cm, yellow-colored, lobulated mass in the submucosal layer. F. Photomicrograph reveals scattered epithelial tissue (arrow) and the surrounding abundant fat tissue (hematoxylin-eosin stain, × 40; left). High-power photomicrograph of epithelial tissue shows ductal structure (arrow) and the acini (star), compatible with heterotopic pancreas (hematoxylin-eosin stain, × 200; right).
