Preoperatively diagnosed mucocele of the appendix
Abstract:
Mucocele of the appendix is an infrequent entity, characterized by distension of the lumen due to accumulation of mucoid substance and is rarely diagnosed preoperatively. If untreated, mucocele may rupture producing a potentially fatal entity known as pseudomyxoma peritonei. The type of surgical treatment is related to the dimensions and the histology of the mucocele. Appendectomy is used for simple mucocele or for cystadenoma. Right hemi-colectomy is recommended for cystadeno carcinoma. In this paper, we report a case of an asymptomatic 37-year-old woman in whom mucocele was found on a routine ultrasound examination and preoperative computed tomography scan. Surgery revealed a big appendix measuring 84 mm in length and 40 mm in diameter. The final pathologic diagnosis was simple mucocele.
Insights
A mucocele of the appendix is a rare condition causing lumen distension. This case highlights a simple mucocele found incidentally in an asymptomatic patient, emphasizing the importance of diagnostic imaging.
Area of Science:
- Gastroenterology
- Surgical Pathology
Background:
- Mucocele of the appendix is an uncommon condition characterized by mucus accumulation within the appendiceal lumen.
- It is frequently asymptomatic and diagnosed incidentally, posing a risk of rupture leading to pseudomyxoma peritonei if left untreated.
Observation:
- This report details a case of a 37-year-old asymptomatic female.
- Incidental diagnosis was made via routine ultrasound and confirmed with computed tomography scan.
- Surgical exploration revealed an enlarged appendix (84 mm x 40 mm).
Findings:
- The final pathological diagnosis was a simple mucocele of the appendix.
- The size of the appendix was significantly increased due to the mucoid substance accumulation.
Implications:
- This case underscores the utility of imaging modalities like ultrasound and CT scans in the preoperative diagnosis of appendiceal mucocele.
- Management strategies, including appendectomy or right hemicolectomy, are dictated by the mucocele's size and histological findings.
- Early detection and appropriate surgical intervention are crucial to prevent complications such as pseudomyxoma peritonei.

Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
