case_images: Preoperative contrast-enhanced CT scan (Figs. 1 and 2) showed a wide and severe thickening of the appendiceal walls with extensive soft-tissue stranding and inflammation of the peri-appendicular fat.
case_images: Coronal CT multiplanar reconstruction confirms the presence of an enlarged appendix with severe peri-appendiceal and peri-cecal inflammation and fat stranding and associated intra-mural air (white arrows)

case_images: Preoperative contrast-enhanced CT scan (Figs. 1 and 2) showed a wide and severe thickening of the appendiceal walls with extensive soft-tissue stranding and inflammation of the peri-appendicular fat.
case_images: Low-power view of mucinous and "signet ring cells" adenocarcinoma in the wall of the appendix with lakes of mucin. Normal glands and lymphoid tissue are present (arrow) (HE, x40). Inset: High-power view of the signet ring cells that penetrated the peri-appendiceal fatty tissue. (HE, x400)

case_images: The final histological diagnosis was consistent with well-differentiated infiltrating adenocarcinoma of the appendix with mucinous and "signet ring cells" appearance, with signs of infiltration of peri-appendicular fat and a peritoneal abscess (Fig. 3).
