Cause of Ascites?

Think this is an interesting CT scan of abdomen.

A lady was admitted to medical for "Ascites for invesigation" - as usual, everything under the sun will be "for medical to find out". She complained of progressive abdominal distension and discomfort, and there was a vague mass felt on abdominal palpation.

What do you think the CT (circled area) shows? (You can click to enlarge)

Quoting my friend:

This patient might not be in the right place.. she should be in general surg ward.

Though this is really wild - ectopic pregnancy with implantation at mesentery/small intestine.

hui: Cysticercus cellulosae affecting more of muscles and CNS right? But wow tat's a cool diagnosis - I guess you're doing pathology/ parisitology sem now hehe=)

shay: You're right that she's in the wrong ward - she should be in gyne ward actually - but it's not ectopic preg. Anymore guess?

My guess -

Ovarian cancer. with intraperitoneum spread.

Darren Lee said...

Excellent! Yes she has an ovarian Ca which spreads to the omentum. There's a name for the classical CT appearance, do you know? ;)

-hui- said...

yah.. but it kinda looks like it.. lol. oh well.. too much of parasitolgy i think.

shay said...

I only know the omental cake appearance in surgery. Is that the radiological description?

Darren Lee said...

Yup that's the answer!
The scan shows a grossly abnormal and thickened omentum, giving the appearance of an "Omental cake".

Differential diagnoses of omental cakes:

Malignancy: Ovarian, gastric, colonic, lymphoma etc

Inflammatory: TB, Crohn's disease

Benign: Sclerosing mesenteritis, desmoid fibroma

This lady had an ovarian Ca. She was then taken over by gyne team.

Surprised that a vague mass palpable per abdomen didn't land up in my ward...casualty nowadays have this problem of admitting the wrong patient to the wrong ward.
