Appendiceal Mucocele - A Review of Literature with a Case Report

Abstract

Background: Appendiceal mucoceles represent neoplastic and non-neoplastic, dilatated, mucus filled appendix vermiformix. Appendectomy is obligatory due to a possible malignancy. It is crucially important to avoid rupturing of the mucocele because it can result in pseudomyxoma peritonei, with high morbidity and mortality. Case Report: We presented a 52-year-old man with pain and palpable mass in the lower right quadrant of the abdomen. The mucocele was removed without a rupture, and the patient was discharged from the surgical department one day after the surgery without a complication. Discussion: The resection must be done very carefully, because the rupture of a mucocele can cause pseudomyxoma peritonei, a very dangerous and often lethal condition. Due to the concern of rupture, we performed the classical resection through laparotomy. Conclusion: It is very important, especially for young, inexperienced surgeons to be aware of this rare diagnosis and perform a surgical intervention according to the guidelines of good clinical practice.

Appendix diverticulosis in a patient diagnosed on pathology after laparoscopic appendectomy for appendicular mucinous mass—case report and literature review

“…Appendicular mucocele most likely to be in elderly women with variable presentations, which differ from AD that tends to be asymptomatic in male patient unless they present with inflammatory changes [ 9 ]. Images might help in the differentiation between AD and MAN; the classical CT abdomen finding of AD is: appendiceal diverticulum with hyperdense pericaecal fat [ 2 ] compared with a thin capsulated cystic mass in the right lower quadrant with low attenuation and wall calcification for MAN [ 10 ]. Colonoscopy also has some ability in identifying appendicular mucocele if the appendiceal orifice is seen at the center of the mound, which is known as ‘Volcano sign’ [ 11 ].…”
