[Peritoneal pseudomyxoma. Diagnostic role of CT and ultrasonics]
Abstract:
Pseudomyxoma peritonei is an uncommon disorder, usually the sequelae of mucocele or mucinous adenocarcinoma of the appendix or mucinous cistoadenocarcinoma of the ovary. Two cases of pseudomyxoma peritonei were examined by ultrasound and one case by CT. US revealed, in a case, multiple echogenic small masses scattering on the peritoneal surface or floating in ascites. CT showed, in the second case, a huge mass consisting of a low attenuation material with internal septation. Also a perforation of intestinal loops in the mass was demonstrated. CT and US appearance of pseudomyxoma peritonei in our experience and in previously reported cases are discussed.
Insights
Pseudomyxoma peritonei, a rare condition often linked to appendiceal or ovarian tumors, presents distinct imaging findings. Ultrasound and CT scans reveal characteristic peritoneal masses and ascites, aiding diagnosis of this uncommon disorder.
Area of Science:
- Gastroenterology and Radiology
Background:
- Pseudomyxoma peritonei is a rare clinical entity.
- It typically arises from appendiceal mucinous neoplasms or ovarian mucinous cystadenocarcinomas.
Observation:
- Two cases of pseudomyxoma peritonei were evaluated using diagnostic imaging modalities.
- Ultrasound (US) demonstrated multiple echogenic peritoneal masses and ascites.
- Computed Tomography (CT) revealed a large, low-attenuation mass with internal septations and intestinal perforation.
Findings:
- Imaging findings in pseudomyxoma peritonei can vary.
- US and CT exhibit characteristic patterns that aid in diagnosis.
- The study discusses the appearance of pseudomyxoma peritonei in the context of prior literature.
Implications:
- Accurate imaging diagnosis is crucial for managing pseudomyxoma peritonei.
- Understanding the characteristic US and CT findings can improve diagnostic accuracy.
- Further research into imaging features may refine diagnostic and treatment strategies.
