(A-B) A HP in duodenal papilla. The coronal image in portal venous phase showed a 3 cm, ovoid and ill-defined lesion (white arrow) with intraluminal growth pattern, presented marked and heterogeneous enhancement totally. A single-opening duct-like structure that opened into the duodenal lumen was showed in the MRCP image (red arrowhead). (C-D) A HP located in posterior wall of the gastric antrum. The sagittal CT image in arterial phase showed a 2.6 cm, hill-like submucosal lesion (orange arrow) with intraluminal growth pattern, and demonstrated peritumoral hypodensity line, surface ulceration (white arrowhead). The axial T1-weighted MR image showed similarly a broad- based, microlobulated (*) lesion with isointensity
