Diagnostic Ultrasound - Abdomen and Pelvis

Peritoneal Carcinomatosis
Diagnoses: Abdominal Wall/Peritoneal Cavity
(Left) Transverse ultrasound of
the upper abdomen shows a
thickened heterogeneous
omentum ſt with underlying
bowel st. Core biopsies
showed mucinous
adenocarcinoma. (Right) Axial
CECT of the same patient
shows the extent of the
omental cake ſt. The
omentum contains soft tissue
and fat densities. A large
amount of ascites st is
present.
(Left) Panoramic transverse
ultrasound (same patient) of
the upper abdomen shows the
extent of the hypoechoic
omental cake ſt displacing
bowel posteriorly. (Right)
Axial NECT of a patient with a
renal transplant and
abdominal distension ſt
shows an extensive omental
cake displacing bowel .
Ascites st is mild. Omental
biopsy confirmed ovarian
carcinoma.
(Left) Axial NECT of the same
patient confirms thickening of
the peritoneum ſt and a large
pelvic mass st. The lower
pole of a renal transplant is
noted. (Right) Transvaginal
ultrasound of a patient with
ovarian carcinomatosis shows
that in the left adnexa there is
a soft tissue plaque ſt along
the peritoneum as well as a
solid mass st. Surrounding
ascites contains low-level
echoes .
