Diagnostic Ultrasound - Abdomen and Pelvis

Chronic Pancreatitis
(Left) Transverse ultrasound
shows parenchymal
calcifications in the enlarged
pancreatic head ſt. There is
pancreatic ductal dilatation
in the atrophic body and
tail . Also note the dilated
common bile duct st.
Pancreatic margins are
indistinct. (Right) CT in the
same patient demonstrates
the enlarged pancreatic head
with numerous parenchymal
calcifications .
Peripancreatic edema ſt and
loss of distinct margins are
suggestive of acute on chronic
pancreatitis.
Diagnoses: Pancreas
(Left) Transverse ultrasound
demonstrates multiple
enlarged parenchymal
calcifications in the body of
the pancreas. The parenchyma
ſt is atrophic and
heterogeneous, with indistinct
margins. (Right) CT scan in the
same patient shows
calcifications in the
pancreatic head and neck, as
well as a large intraductal
calculus in the distal MPD .
Enlargement of the pancreatic
head can mimic neoplasm.
(Left) Transverse ultrasound
demonstrates an atrophic,
echogenic gland with
intraductal and
parenchymal ſt calcifications.
The distal body/tail are
obscured by bowel gas. (Right)
Transverse T2-weighted MR in
the same patient shows ductal
dilatation in the body and tail
better than on the US.
Intraductal stones are
visible as signal voids.
