Figure 1 Computed tomography images. A: Axial enhancement, cystic mass in the right iliac fossa, gourd-shaped, smooth margin, slight enhancement of cystic wall, slight delayed enhancement of mural nodules, and no enhancement of intracystic fluid (arrow); B. Coronal reconstruction showing that the lesion was located in the right lower abdominal ileocecal region and connected with the cecum wall (arrow); C: Pathological specimen showing the general view of the resected mass (at the arrow is the root of the appendix).

Figure 2 Histological analysis. A: Low-grade display of the entire appendix (arrow pointing to epithelium) (4×); B: Low-grade lesions show a single layer of epithelium with a myxoid lake between the muscular layers (arrow pointing to the myxoid lake) (10×); C: The luminal epithelium with low-grade features without cytological atypia (arrow pointing to the epithelial cells) (40×); D: Low-grade CK stained epithelial cells, with no obvious infiltrating epithelial floating in the mucus lake (10×).
