Mucocele of the appendix on screening CT colonography: a case report

Abstract

An asymptomatic mucocele of the appendix has been previously described on such modalities as optical colonoscopy, conventional CT, ultrasound, and barium enema, but only one case has been previously reported on CT colonography (CTC) [1]. We present a case where an asymptomatic adult undergoing a screening CTC was found to have an appendiceal mucocele. Although the overall number of significant extracolonic findings on screening CTC is very low, a mucocele of the appendix is a notable exception because the presence of this lesion results in surgical intervention while failure of diagnosis can lead to patient morbidity.
