Abstract:
A mucocele is a cystic dilatation of the vermiform appendix that contains mucous material. The symptoms associated with it are not specific and the diagnosis is seldom made prior to surgery. The reported prevalence in appendectomy specimens procured during surgery is 0.2-0.3%. Recently, we experienced a case of patient with appendiceal mucocele detected by colonoscopic examination. This case did not show typical colonoscopic features of a mucocele, demonstrating protrusion of mucin, in the absence of a smooth mound with normal overlying mucosa surrounding the appendiceal orifice. The case involved a 64-year-old woman who underwent a colonoscopy. An abdominopelvic computed tomography scan suggested a normal appendix. Subsequently, we performed an appendectomy. The pathologic finding was a low-grade appendiceal mucinous neoplasm.
