From: Insight into gastrointestinal heterotopic pancreas: imaging evaluation and differential diagnosis
a–c Heterotopic pancreas in a 61-year-old female. Axial contrast-enhanced CT images obtained during the plain (a) /arterial (b) /venous (c) phases showed a heterogeneous enhanced flat mass (white arrows) in the gastric antrum. The mass had an endoluminal growth pattern, which is more common with heterotopic pancreatic lesion in the stomach. d–f Gastrointestinal stromal tumor in a 41-year-old male. Axial contrast-enhanced CT images obtained during the plain (d) /arterial (e) /venous (f) phases also showed a homogeneous enhancing round mass (white arrows) in the gastric antrum with the same endoluminal growth pattern
