Abstract: Low-grade appendiceal mucinous neoplasms (LAMN) constitute a rare subset of epithelial tumors and represent the second most common form of appendiceal cancer. LAMN typically presents as acute appendicitis, with definitive diagnosis often occurring incidentally during appendectomy surgery. While contrast-enhanced computed tomography (CECT) is the imaging of choice, misdiagnoses are common, highlighting the need for additional diagnostic modalities that are often underutilized. There is ongoing debate about treatment recommendations which typically involve a simple appendectomy, but controversy persists regarding the intraoperative necessity of a cecectomy, ileocecectomy, or formal right hemicolectomy. Here, we present a case featuring a 72-year-old African American female referred to our surgery clinic presenting solely with bloating and constipation rather than classical acute appendicitis, discrepancies between CT and MR imaging, and an unusual intraoperative finding of a posteriorly positioned mucocele adhered to the cecum, necessitating right hemicolectomy.
