Objective:
To improve capability of appendiceal mucocele diagnosis via analyzes its clinical, pathological basis and radiological results.
Methods:
Summarize 18 cases with pathological diagnosed appendiceal mucocele in PUMC Hospital since January 1985 till september 2004, including 4 males and 14 females (1:3.5), age ranged from 31 to 78 yrs old (average 59.8 years old). Eleven cases underwent barium enema, in which 9 cases received abdominal CT scanning and 1 case received CT virtual colonography.
Results:
(1) CLINICAL RESULTS: 8 cases (44.4%) had right lower abdominal pain, 12 cases (66.7%) had palpable abdominal mass. (2) Radiological results: barium enema showed extrinsic oppressed filling defect at the end of cecum without destruction of mucosa; CT scanning showed right lower abdominal cystic mass, 75% with cystic wall calcification, massive septal mucous ascites was seen in one case with pseudomyxoma peritonei; CT virtual colonography showed clearly the extra cavity and intracavity changes at cecum. (3) Pathological results: simple mucocele (4 cases, 22.2%), mucous cystadenoma (12 cases, 66.7%) and mucous cystadenocarcinoma (2 cases, 11.1%)
Conclusion:
There are four pathological types in appendiceal mucocele. Radiological characters of appendiceal mucocele have distinct specificities while its clinical ones not. Radiological procedures are vital for correct clinical diagnosis.
Insights
Appendiceal mucocele diagnosis is improved by analyzing clinical, pathological, and radiological findings. Radiological procedures are crucial for accurate diagnosis due to distinct imaging characteristics.
Area of Science:
- Gastroenterology
- Radiology
- Pathology
Context:
- Appendiceal mucoceles are rare, and their diagnosis can be challenging.
- Understanding the clinical, pathological, and radiological features is essential for accurate diagnosis.
Purpose:
- To enhance the diagnostic capability for appendiceal mucoceles.
- To analyze the clinical presentation, pathological basis, and radiological findings of appendiceal mucoceles.
Summary:
- A review of 18 appendiceal mucocele cases (1985-2004) revealed common clinical signs like abdominal pain and mass. Radiological imaging, including barium enema, CT scans, and CT virtual colonography, showed specific features such as cystic masses and calcifications. Pathological examination identified four types: simple mucocele, mucous cystadenoma, and mucous cystadenocarcinoma.
Impact:
- Radiological findings possess distinct specificities for appendiceal mucocele diagnosis, unlike clinical signs.
- Radiological procedures are vital for achieving correct clinical diagnoses of appendiceal mucoceles.
