Accurate diagnosis of omental disease relies on understanding the greater omentum's embryology, anatomy, and pathology. This review highlights key imaging findings to aid clinicians in identifying and evaluating omental pathologies.

Area of Science:

  • Radiology
  • Gastrointestinal Imaging
  • Surgical Anatomy

Background:

  • The greater omentum is a complex peritoneal fold with significant roles in immunity and metabolism.
  • Its intricate embryologic development and anatomical variations can complicate diagnostic interpretation.
  • Omental pathologies range from benign conditions to malignant neoplasms, necessitating accurate imaging evaluation.

Purpose of the Study:

  • To elucidate the embryologic origins and detailed anatomic relationships of the greater omentum.
  • To comprehensively review the spectrum of imaging findings associated with common and rare omental diseases.
  • To provide a framework for accurate diagnosis of omental pathologies based on characteristic imaging features.

Main Methods:

  • Review of relevant scientific literature on omental embryology, anatomy, and pathology.

Related Experiment Videos

  • Analysis of a diverse range of imaging modalities including ultrasound, CT, and MRI.
  • Correlation of imaging findings with histopathologic diagnoses where available.

    • Main Results:

    • Detailed description of the embryologic fusion planes and adult anatomical configurations of the greater omentum.
    • Categorization of omental diseases based on imaging characteristics (e.g., inflammatory, neoplastic, cystic).
    • Illustrative examples of imaging findings for conditions such as omental infarction, desmoid tumors, and carcinomatosis.

    Conclusions:

    • A thorough understanding of omental embryology and anatomy is fundamental for interpreting imaging studies.
    • Recognizing specific imaging patterns facilitates the accurate diagnosis of various omental diseases.
    • This review serves as a valuable resource for radiologists and clinicians managing patients with omental abnormalities.
