Diagnostic Ultrasound - Abdomen and Pelvis

Pancreatic Neuroendocrine Tumor
(Left) Coronal CECT shows a
large heterogeneous,
hypodense mass ſt in the
pancreatic head with
intratumoral calcification st,
which is suggestive of
malignancy. Note the
pancreatic ductal dilatation
due to mass effect in the head
of the pancreas . (Right)
Corresponding endoscopic
ultrasound shows a wellcircumscribed,
hypoechoic,
solid mass ſt in the pancreas.
Diagnoses: Pancreas
(Left) Axial CECT
demonstrates a large
hypervascular mass ſt in the
pancreatic head with a small,
focal hypoattenuating area of
central necrosis st. (Right)
Corresponding endoscopic
ultrasound demonstrates a
lobulated, well-circumscribed
isoechoic solid mass ſt
containing a focal hypoechoic
area of cystic change st.
(Left) Axial T2 true FISP MR
demonstrates a wellcircumscribed
mass ſt in the
body of the pancreas with 2
T2 bright components. Note
the lack of pancreatic ductal
dilatation in the normalappearing
pancreatic
parenchyma distal to the mass
. (Right) Axial T1 C+ FS MR
in the same patient shows
peripheral enhancing tumor in
the medial aspect of the mass
ſt, while the cystic/necrotic
lateral component is
nonenhancing st.
