Diagnostic Ultrasound - Abdomen and Pelvis

Approach to Sonography of Abdominal Wall/Peritoneal Cavity
(Left) Longitudinal ultrasound
of the right upper quadrant
shows a large amount of
simple ascites in Morison
pouch . The liver transplant
surface ſt was smooth.
(Right) Transverse ultrasound
of the right lower quadrant
shows septated ſt ascites
secondary to prior
hemorrhage from a ruptured
spleen. Septa may preclude
therapeutic drainage.
Diagnoses: Abdominal Wall/Peritoneal Cavity
(Left) Longitudinal highresolution
ultrasound of the
anterior abdominal wall shows
2 peritoneal metastases ſt
growing through the
abdominal wall. There was
also ascites st from
metastatic pancreatic
carcinoma. (Right) Transverse
color Doppler ultrasound of
the right upper quadrant
shows a plaque of soft tissue
ſt against the peritoneum.
Color flow was present in this
omental cake from mucinous
carcinoma. Ascites st
increases sensitivity for
detection of peritoneal
metastases.
(Left) Transverse ultrasound of
the right lateral mid abdomen
shows echogenic ascites st
from acute hemorrhage. There
were multiple hepatocellular
carcinomas in this cirrhotic
patient. Normal bowel ſt is
noted. (Right) Transverse
ultrasound of the left lower
quadrant shows complex
ascites st from
carcinomatosis. There are
thick, irregular septa with
adherent bowel ſt.
