Case Discussion

The pathological analysis of the appendectomy specimen revealed a mucocoele caused by a mucinous cystadenoma, with a small focal rupture. Due to comorbidities, no further treatment was undertaken, This CT reveals extensive and disseminated malignancy in the form of pseudomyxoma peritonei. Large pools of gelatinous material fill the abdominal cavity and classically cause scalloping of the surface of the liver. Small foci of calcification are often seen scattered around the abdomen.
