Fig. 2

Images depict non-SMAD4-mutated PDAC located in the head of the pancreas with a CA19-9 level of 1819.0 U/mL. The series includes unenhanced transverse images(a), contrast-enhanced images in the arterial phase (b), venous phase(c), and delayed phase (d) T1W images, illustrating a 2.2-cm mass without rim enhancement (arrows). (e) MRCP illustrates dilation of the common bile duct (CBD). (f) SMAD4 immunostaining reveals negative expression in the nuclei of the tumor cells (scale bar = 30 μm)
