Mucocele of the appendix: computed tomographic, endoscopic, and pathologic correlation
1Department of Medicine, University of North Carolina School of Medicine, Chapel Hill.
Abstract:
Mucoceles of the appendix are a rare group of lesions thought to occur as a sequelae of luminal obstruction as well as certain benign and malignant neoplasms of the appendix. Early, preoperative diagnosis is rare. We report a case of an appendiceal mucocele in which the diagnosis was suggested by computed tomographic imaging and colonoscopy, and confirmed at surgery. Radiologic, endoscopic, and pathologic correlations of this rare entity are discussed.
Insights
Appendiceal mucoceles are rare, often diagnosed late. This case highlights how computed tomography and colonoscopy can aid in early diagnosis of these appendiceal lesions.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Diagnostic Imaging
Background:
- Appendiceal mucoceles are uncommon lesions.
- They are associated with appendiceal obstruction and neoplasms.
- Preoperative diagnosis remains challenging.
Observation:
- A case of appendiceal mucocele is presented.
- Computed tomographic (CT) imaging suggested the diagnosis.
- Colonoscopy also provided diagnostic clues.
Findings:
- The diagnosis was confirmed intraoperatively.
- Radiologic, endoscopic, and pathologic findings were correlated.
- This case emphasizes the utility of multimodal diagnostic approaches.
Implications:
- Early diagnosis of appendiceal mucoceles is possible with advanced imaging and endoscopy.
- Multidisciplinary correlation improves diagnostic accuracy for rare appendiceal conditions.
- Timely diagnosis facilitates appropriate surgical management.
