CT of pseudomyxoma peritonei: case report

|January 1, 1984
Abstract:
Pseudomyxoma peritonei is an uncommon disorder, which is usually the sequelae of mucocele of the appendix or mucinous ovarian cystadenocarcinoma. The characteristic CT findings of massive ascites, loculated fluid collections, hepatic and mesenteric scalloping caused by low attenuation tumor masses, without lymphadenopathy and in the presence of intrinsically normal viscera strongly suggest the diagnosis.
Insights
Pseudomyxoma peritonei is a rare condition often stemming from appendiceal or ovarian tumors. Characteristic CT scans show widespread fluid, scalloping, and low-attenuation masses, aiding diagnosis.
Area of Science:
- Radiology
- Oncology
- Gastroenterology
Background:
- Pseudomyxoma peritonei is an uncommon neoplastic disorder.
- It typically arises as a sequela of appendiceal mucocele or ovarian mucinous cystadenocarcinoma.
Observation:
- The condition presents with distinctive imaging features on computed tomography (CT).
- Key CT findings include massive ascites and loculated fluid collections.
Findings:
- Hepatic and mesenteric scalloping, caused by low attenuation tumor masses, are characteristic.
- Absence of lymphadenopathy and normal appearance of viscera are also noted.
Implications:
- These specific CT findings strongly suggest the diagnosis of pseudomyxoma peritonei.
- Early and accurate diagnosis is crucial for appropriate patient management and treatment planning.
