Correlation of CT enhancement, tumor angiogenesis and pathologic grading of pancreatic carcinoma

Figure 4 A 70-year-old woman with solid-cystic-papillary well-differentiated pancreatic carcinoma with involvement of ligamentum hepatoduodenale. A: Helical CT enhancement imaging 35 s after administration of contrast agent revealed that CT enhancement of mass was heterogenously slight low density with low density necrotic region; B: Hematoxylin-eosin-stained specimen (100 ×) demonstrated massive necrosis tissuse and irregular tubula structure in well-differentiated pancreatic carcinoma.
