What is a omental nodule?

Early omental disease manifests as a smudged or permeated appearance of the omental fat (Fig. 3a). 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].

Can peritoneal nodules be benign?

Introduction: Leiomyomatosis peritonealis disseminata (LPD) is a peculiar benign clinical disorder characterized by proliferation of peritoneal and subperitoneal nodules. LPD is a difficultly diagnosed benign disease that rarely degenerates into malignancy.

What causes peritoneal nodules?

Peritoneal carcinomatosis most often develops when other abdominal tumors spread to the peritoneum, leading to multiple new tumors on the surface of this membrane. If you get peritoneal carcinomatosis, it generally means that your abdominal cancer is in an advanced stage.

Can nodules in omentum be benign?

If the OS was ≤5, the omental lesion was considered to be benign, with a malignant rate of 0%. If the omentum is inflamed, patients often have abdominal pain, fever, and other symptoms.

Can peritoneal nodules be removed?

Surgery. Surgery not only helps with diagnosis. It may also remove any tumors. To stage and treat this cancer, a surgeon removes all visible disease.

Is omentum considered peritoneal metastasis?

Controlling metastases remains a critical problem in cancer biology. Within the peritoneal cavity, omental tissue is a common site for metastatic disease arising from intraperitoneal tumors; however, it is unknown why this tissue is so favorable for metastatic tumor growth.

What is omental peritoneal disease?

The peritoneal cavity, especially the omentum, is a common site for gastric cancer metastasis, representing advanced disease stage and poor prognosis.

Does the omentum show on CT scan?

Imaging. On CT, the normal greater omentum appears as a band of fatty tissue with variable width.

Does omentum have lymph nodes?

DISCUSSION. The greater omentum contains groups of lymph nodes (level 4ab along the left gastroepiploic vessels and level 4d along the right gastroepiploic vessels) and lymphatic ducts for adequate drainage, which makes GOLF a good alternative choice for donor lymph node transfer.

What is omental metastasis?

Cancer cells that have broken away from the ovary like to implant and grow there—this is known as omental metastasis.
