CT and MR imaging patterns for pancreatic carcinoma invading the extrapancreatic neural plexus (Part II): Imaging of pancreatic carcinoma nerve invasion

Figure 1 Examples of patterns of extrapancreatic neural invasion by pancreatic carcinoma visualized by computed tomography. A: Sixty-three-year-old male with pancreatic carcinoma in the pancreas body. Contrast-enhanced computed tomography (CT) images during the arterial dominant phase show strand-like structure (arrow) around the superior mesenteric artery; B: Sixty-seven-year-old female with pancreatic carcinoma in the pancreas head. Contrast-enhanced CT images during the arterial dominant phase show strand-like structure (arrow) around celiac trunk; C: Histopathology confirmed extrapancreatic neural (asterisk) invasion by pancreatic carcinoma (arrows) (HE, 200 ×); D: Histopathology confirmed extrapancreatic neural (asterisk) invasion by pancreatic carcinoma (arrows) (HE, 200 ×).
