Appendiceal Mucocele Presenting as a Cecal Bulge on Surveillance Colonoscopy.

Appendiceal mucoceles are rare tumors with diverse presentations and clinical implications. Generally, mucoceles are discovered on imaging or intraoperatively, but, rarely, can be found on colonoscopy. Appendectomy is the recommended next step in management, followed by subsequent treatment according to guidelines dictated by pathology findings. We present the case of a 52-year-old female undergoing routine colonoscopy screening who had incidental findings of a cecal bulge at the appendiceal orifice. The patient was entirely asymptomatic with an unremarkable medical history. Further workup suggested appendiceal mucocele and she was referred to surgery. After an appendectomy, pathology confirmed simple appendiceal mucocele. The patient made a full recovery and continued routine colonoscopy screening. This case demonstrates the variance in the clinical presentation of appendiceal mucocele and the possibility of discovery on routine screening colonoscopy.
