case_images: Sagittal (a) and axial (b,c) abdominal CT scan in aortic phase show a SMAS : Acute angulation of the superior mesenteric artery (12  ) (a) , with reduced aortomesenteric distance (3,7 mm) (b) resulted in compression of the third portion of the duodenum, leading to dilatation of the proximal duodenum (arrow in c).

case_images: Proximal duodenal dilatation was observed with an SMA-aorta distance of 3.7 mm (Figure 1).
case_images: Axial computed tomography scan images in arterial phase show acute necrotizing pancreatitis involving only the peripancreatic tissues CT scan images in arterial phase showing the enhancement of the entire pancreatic parenchyma (white star) associated with heterogeneous peripancreatic collections (blue stars), fully encapsulated, containing area of fat (white arrow), fluid density, and areas with greater attenuation (blue arrow) compatible with walled-off necrosis.
