Although rare, the “cup and ball” sign is a characteristic imaging finding seen when an appendiceal mucocele intussuscepts into the large intestine (cecum) [1]. The “cup” is formed by the dilated appendix, and the “ball” is formed by the base of the dilated appendix intussuscepting into the cecum (Fig. 1a, b) recalling the appearance of the “cup and ball” toy (Fig. 2).

A Coronal and B sagittal contrast enhanced CT images of the abdomen show an appendiceal mucocele forming the cup (arrowhead), the base of which is intussuscepting into the cecum forming the ball (arrow). This was surgically confirmed to be an appendix mucocele (secondary to a low grade mucinous neoplasm of the appendix) intussuscepting into the cecum
