The mucocele of the appendix is an uncommon disorder which is often asymptomatic but sometimes causes acute appendicitis-like symptoms. In this article, we present a case of appendicitis complicated with plastrone which appendectomy was performed. The histopathological examination revealed appendicular mucocele formation due to the intussusception. Preoperative suspicion and diagnosis of appendiceal mucocele are important. Ultrasonography and computed tomography are useful tools for the diagnosis of appendiceal mucocele. It may be also detected by colonoscopy as a smooth submucosal lesion in the cecum. Preoperative diagnosis is paramount to minimize intraoperative and postoperative complications.
