Diagnostic Ultrasound - Abdomen and Pelvis

Peritoneal Carcinomatosis
(Left) Transverse ultrasound
shows gelatinous ascites ſt in
pseudomyxoma peritonei.
Mobile echoes were seen in
real-time, confirming the
liquid content. Bowel is
displaced . (Right)
Transverse ultrasound of the
right lower quadrant shows
ascites and multiple peritoneal
nodules ſt from recurrent
native kidney renal cell
carcinoma in a renal
transplant recipient.
Diagnoses: Abdominal Wall/Peritoneal Cavity
(Left) Axial CECT in a patient
with metastatic pancreatic
neuroendocrine tumor shows
multiple peritoneal nodules ſt
of varying sizes with ascites.
There is infiltration of the
omentum . (Right)
Longitudinal ultrasound of the
right abdomen shows ascites
st around the liver ſt and
outlining a solid
intraperitoneal metastasis
from recurrent renal cell
carcinoma.
(Left) Transverse ultrasound of
the pelvis in a patient with
pseudomyxoma peritonei from
appendiceal adenocarcinoma
shows ascites contains
multiple low-level echoes ſt
and exerts mass effect on the
small bowel . Pushing and
releasing the transducer will
induce jiggling of the ascites.
(Right) Axial CECT of the same
patient shows septations in
the low-density gelatinous
ascites ſt with subtle
calcifications st. The small
bowel is clumped .
