A review of her past imaging included a computed tomography (CT) aorta and abdomen/pelvis which also revealed this anatomic variant and appeared unchanged over the span of approximately nine months (Figures 1 and 2).
Multiple contrast enhanced axial images of the pelvis demonstrate a circular hypodense structure arising from the base of the cecum extending into the fluid-filled cecal lumen. Incidentally noted pelvic ascites are present.

Coronal, axial, and sagittal contrast enhanced CT image demonstrates a polypoid mass in the base of the cecum representing a cecoappendiceal intussusception, mimicking a polyp or neoplasm.
