3. • Fig GI 81-1 Carcinoma of the pancreas.
Longitudinal sonogram demonstrates an irregular
mass (M) with a semisolid pattern of intrinsic
echoes. There is associated dilatation of the
intrahepatic bile ducts (arrows). (A, aorta.)162

4. • Fig GI 81-2 Pancreatic carcinoma with liver
metastases. Transverse sonogram shows an
enlarged liver containing multiple metastatic
lesions (arrowheads).95

5. • Fig GI 81-3 Pancreatic carcinoma with lymph
node metastases. Diffuse enlargement of the
pancreas (P) with enlarged hypoechoic
paravascular lymph nodes (LN) that obscure
the aorta and inferior vena cava.95

6. Fig GI 81-4 Islet cell tumor. This cystic mass in the head of the
pancreas shows acoustic enhancement without evidence of
debris.163

7. • Fig GI 81-5 Mucinous cystic neoplasm. Multiloculated
cystic mass with echogenic internal septa within the
tail of the pancreas. Echogenic foci with shadowing
that correspond to calcifications are noted along the
septa (arrow). Note the low-level internal echoes.164

8. • Fig GI 81-6 Serous cystadenoma. Sonogram
shows a mass of low echogenicity due to the
interfaces between the tiny cysts. Note the
increased through transmission posterior to
the mass.165

9. • Fig GI 81-7 Pancreatic pseudocyst. Longitudinal
sonogram of the right upper quadrant demonstrates an
irregularly marginated pseudocyst (PC) with acoustic
shadowing (arrow). (L, liver.)

10. Fig GI 81-8 Pancreatic pseudocyst. An erect sonogram
demonstrates a fluid-debris level (arrow) in the pseudocyst. 1(L,
left kidney.)

11. • Fig GI 81-9 Pancreatic phlegmon. Transverse
sonogram shows a hypoechoic mass (M) in the
peripancreatic region.95

12. • Fig GI 81-10 Cystic fibrosis. Transverse sonogram
at the level of the pancreatic head (P) shows
complete fibrofatty replacement of the gland
with absence of normal tissue. Note the multiple
cysts (*) of different sizes adjacent to the liver (L)
and stomach (St).166
