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

Figure 8 Characteristics of tumor and the extrapancreatic neural invasion by pancreatic carcinoma on magnetic resonance images in an 80-year-old female. The tumor was located at the region between head and body of the pancreas and invaded medial to pancreas forming a mass (arrows). A: 3D gradient-echo (GRE) T1-weighted precontrast image; B: Fat-saturated fast recovery fast spin-echo T2-weighted image; C and D: 3D GRE T1-weighted Gd-enhanced arterial and venous phases. Histopathology confirmed extrapancreatic neural invasion by pancreatic carcinoma (arrows); E: HE, 40 ×; F: HE, 200 ×.
