Case Report of Mucocele Appendix

Mucocele of appendix, a descriptive term which implies a dilated appendiceal lumen caused by abnormal accumulation of mucus, is a rare clinical entity; the reported prevalence in appendectomy specimens at surgery is 0.2-0.3% andin 8% of appendicealtumors.1 They typically occur in middle-aged patients. In literature there is discordant in gender predominance. Some studies show a female-to-male ratio of 4: 1; other studies describe a similar occurrence in women and men.2, 3, 4 Most common clinical manifestation is a palpable mass in lower right quadrant of abdomen; the patient can present either with or without pain. If a superinfection is present, mucinous cystadenoma may be clinically indistinguishable from nontumoral acute appendicitis.5Some patients are asymptomatic; in these cases, mucoceles are found incidentally when imaging is performed for other reasons or during a laparotomy or laparoscopy. In patients with a mucocele, the risk of developing an adenocarcinoma of colon is six times greater than that of the general population.3 CT imaging shows cystic dilation of appendix with wall calcification. Superinfection and inflammation shows enhancing wall thickening and surrounding stranding and abdominal lymphadenopathy.
