Figure 13a.

Appendiceal mucinous neoplasm in a 64-year-old man with right lower quadrant pain. (a) Coronal contrast-enhanced CT image shows marked distention of the appendix, with heterogeneous internal contents (*) and curvilinear calcification of the appendiceal wall (arrow). (b) Photograph of the intact resected specimen shows a mucin-distended rubbery appendix (*). Histopathologic analysis of the appendiceal wall demonstrated tall columnar mucinous bland epithelium, seen with low-grade appendiceal mucinous neoplasms (LAMNs) (Fig E6).
