Core Tip

Core tip: We report an extremely rare case of mucocele of the appendix due to endometriosis. Although it is uncommon, preoperative diagnosis of the mucocele is important; however, diagnosis is difficult using imaging modalities. We report a more accurate diagnostic possibility using preoperative imaging modalities, such as colonoscopy, ultrasonography, computed tomography, and magnetic resonance imaging. Furthermore, this report is important because it is the first review of the literature for mucocele of the appendix due to endometriosis.
