Introduction: Appendiceal intussusception is an infrequent surgical disease that can present acutely, mimicking acute appendicitis, or chronically with intermittent right lower quadrant pain. Lead points are associated with appendiceal intussusceptions in slightly > 70% of cases. Common lead points are endometriosis, mucinous neoplasm, adenoma, adenocarcinoma, and carcinoid. Surgical therapy is often required to manage the intussusception. In cases of nonreducible appendiceal intussusceptions or those that have a lead point, an appendectomy, ileocecectomy, or right hemicolectomy.
Case Description: We report a case of appendiceal intussusception with an intraoperative finding of a cystic mass and pathologic diagnosis of low-grade mucinous neoplasm in a healthy 23-year-old female patient. She underwent a laparoscopic ileocecectomy.
Discussion: Appendiceal mucinous cystadenoma requires long-term follow-up after resection.
Key Words: Appendiceal intussusception, Mucinous neoplasm.
