Summary
Computed tomography (CT) reveals characteristic signs of pseudomyxoma peritonei, including ascites, organ scalloping, and peritoneal infiltration. Radiologists should recognize these CT findings for accurate diagnosis.
Area of Science:
- Radiology
- Oncology
- Gastroenterology
Background:
- Pseudomyxoma peritonei is a rare condition characterized by mucinous ascites.
- Accurate diagnosis relies on characteristic imaging findings.
Purpose of the Study:
- To describe the computed tomography (CT) imaging features of pseudomyxoma peritonei.
- To aid radiologists in identifying this condition on CT scans.
Main Methods:
- Retrospective review of CT scans from 7 patients.
- Surgical and pathological confirmation of pseudomyxoma peritonei.
Main Results:
- Common CT findings included large-volume ascites with heterogeneous density, hepatic and splenic scallopings, and peritoneal/omental infiltration.
- Omental cakes (3 patients) and appendiceal masses (2 patients) were observed.
- Other findings: calcification, septa, mucinous masses, pleural effusion, ureteral dilation.
Conclusions:
- CT demonstrates distinct characteristics suggestive of pseudomyxoma peritonei.
- Radiologists must be aware of these findings for timely diagnosis.

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:21Peritoneum
The peritoneum is a vital membrane that lines the abdominal cavity and covers most of the organs within it. It plays a crucial role in protecting the organs, providing a smooth surface for their movement, and facilitating various physiological processes. Understanding the anatomy and function of the peritoneum is essential for comprehending the complexities of the abdominal region.

01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
