Detection of peritoneal metastases
1Chelsea and Westminster Hospital, 369 Fulham Road, London SW10 9NH, UK.
Summary
This review explains how peritoneal metastases spread through the abdominal cavity. Advanced imaging techniques like computed tomography are crucial for detecting these metastases by visualizing the complex peritoneal anatomy.
Area of Science:
- Anatomy
- Oncology
- Radiology
Background:
- The peritoneum is the body's largest serous membrane, featuring complex spaces, reflections, ligaments, mesenteries, and omenta.
- Understanding peritoneal fluid dynamics is key to comprehending intraperitoneal disease spread.
- Peritoneal ligaments, mesenteries, and omenta act as conduits and boundaries for metastatic dissemination.
Purpose of the Study:
- To review the detection of peritoneal metastases.
- To elucidate the routes of peritoneal metastasis spread.
- To highlight the role of cross-sectional imaging in visualizing peritoneal anatomy and disease.
Main Methods:
- Review of literature on peritoneal metastasis spread.
- Discussion of imaging modalities for peritoneal cavity visualization.
- Emphasis on computed tomography, sonography, and MR imaging.
Main Results:
- Peritoneal metastases spread via direct extension, ascitic fluid seeding, lymphatic extension, and hematogenous spread.
- Peritoneal ligaments, mesenteries, and omenta are critical pathways for disease dissemination.
- Cross-sectional imaging significantly improves the ability to examine peritoneal anatomy and detect metastases.
Conclusions:
- Accurate visualization of the complex peritoneal anatomy is essential for understanding and detecting peritoneal metastases.
- Advanced imaging techniques have revolutionized the assessment of peritoneal disease spread.
- This review synthesizes current knowledge on peritoneal metastasis detection.
