Fig. 2.56-year-old man with pancreatic cancer. Coronal
volume-rendered three-dimensional multidetector CT scan shows tumor encasement
(arrow) of portal vein. Patient would not be candidate for curative
resection.
Fig. 4.48-year-old man with pancreatic cancer. Coronal volume
rendered three-dimensional multidetector CT scan shows large mass
(arrow) in head of pancreas. Mass is compressing and invading portal
vein. Note bile ductal dilatation.
Fig. 5.67-year-old woman with extensive pancreatic cancer involving
the entire gland. Coronal volume-rendered three-dimensional multidetector CT
scan shows thrombosis of portal vein, splenic vein, and superior mesenteric
veins (arrowheads). Note tumor infiltration (arrow) of
body.
Fig. 6A.48-year-old woman with pancreatic cancer. Coronal
volume-rendered three-dimensional (3D) multidetector CT scan shows tumor
encasement (arrows) of portal confluence. Splenic vein is not
opacified; this finding is compatible with occlusion.
Fig. 6B.48-year-old woman with pancreatic cancer. Coronal
volume-rendered 3D multidetector CT scan obtained at more anterior level than
A shows multiple venous collaterals (arrows).
Fig. 7A.65-year-old woman with pancreatic cancer. Coronal
volume-rendered three-dimensional multidetector CT scan shows large tumor in
pancreatic body (arrow) and tail. Portal vein and superior mesenteric
veins are patent, but splenic vein is not visualized. The latter finding is
compatible with occlusion.
Fig. 8.54-year-old woman with pancreatic cancer. Coronal
volume-rendered three-dimensional multidetector CT scan shows mass arising
from head of pancreas encasing proximal portion of superior mesenteric vein
(arrow).
Fig. 9.45-year-old man with pancreatic cancer. Coronal
volume-rendered three-dimensional multidetector CT scan shows small tumor in
head of pancreas with minimal local invasion (arrow) of superior
mesenteric vein.
