What is an omental cake?
Omental cake is a description given to thickening of the greater omentum secondary to omental peritoneal metastasis. Bulky metastatic deposits in the greater omentum, the so-called omental cake, most often result from ovarian carcinoma or less frequently gastic, pancreatic, or colonic malignancies.
What does omental cake feel like?
In the normal anatomy, omentum looks like bands of fatty tissue with some fine blood vessels while in cases of ascites it appears as thin fatty layer. Soft deposits can appear as seeding. Omental caking is actually a radiological sign which on CT scan can be easily identified as diffuse haziness, or a mass like effect.

What is omental carcinomatosis?
Peritoneal carcinomatosis is the spread of cancer cells inside the abdominal cavity, especially over the peritoneum, the membrane that covers the abdominal cavity. The origin of this cancer is usually intra-abdominal tumors, originating from digestive or gynecological cancers.
What is peritoneal caking?
INTRODUCTION Omental thickening or “caking” is a radiologic sign that frequently indicates advanced peritoneal disease. 1 It may be secondary to malignant, infectious, or inflammatory eti- ologies. Notably, the association between omental caking and ovarian cancer has been well established.
What is staging surgery?
It is determined by examining tissue removed during an operation. This is also known as surgical staging. Sometimes, if surgery is not possible right away, the cancer will be given a clinical stage instead. This is based on the results of a physical exam, biopsy, and imaging tests done before surgery.
What is the meaning of omental?

What is the survival rate of carcinomatosis?
With this technique, the average in disease-free survival is 97.8 months in the first group and 58.8 months in the second. It should be noted that an overall survival of 100% has been observed among patients with low-grade disease.
What is omental cake in the stomach?
In radiology, omental cake is sign indicative of an abnormally thickened greater omentum. It refers to infiltration of the omental fat by material of soft-tissue density. Typically, it is caused by infiltration of metastatic tumours arising from the stomach, ovary, or colon.
What is the pathophysiology of omentum cake?
Enhancing soft tissue nodules form within the omentum as the disease progresses. An omental cake arises when these nodules coalesce to form a diffusely thickened mass and replace the normal fat (Fig. 3b) [6]. Depending on the cause of the omental cake and the extent of intraperitoneal disease, ascites may be an accompanying feature.
What are omental cakes on CT scan?
Omental cakes: unusual etiologies and CT appearances. PATTERNS OF PERITONEAL INVOLVEMENT IN PATIENTS WITH ABDOMINO-PELVIC MALIGNANCIES ON MULTI DETECTOR COMPUTED TOMOGRAPHY An abdominal plain film and a repeat CT scan demonstrated diffuse omental cakeswith air-fluid levels in the small bowel.
What causes omental caking in colon cancer?
Typically, it is caused by infiltration of metastatic tumours arising from the stomach, ovary, or colon. It can also result from tuberculous peritonitis. Another cause is lymphoma, in which omental caking is usually associated lymphadenopathy.
