From: Insight into gastrointestinal heterotopic pancreas: imaging evaluation and differential diagnosis
a, b Coronal and axial enhanced CT images of a heterotopic pancreas in the duodenum of a 53-year-old male showed a 1.3 cm × 0.9 cm, endoluminal lesion (white arrows) with a lobulated margin, presenting round contour on axial image while flat pattern on coronal CT image. Small duct-like structure (black arrow) was seen within the lesion, which measured with a long diameter to short diameter > 1.4 on coronal CT image. c, d Axial enhanced CT images of a heterotopic pancreas in the gastric antrum of a 58-year-old male showed a 1.2 cm × 0.8 cm, oval, ill-defined, and endoluminal lesion (white arrows), with a long diameter to short diameter > 1.4
