The underlying cause can be neoplastic or non-neoplastic. The typical imaging appearance of a mucocele of the appendix is that of a cystic structure with a tubular morphology. This structure is defined by having a blind-ending and being contiguous with the cecum. Radiologists should be familiar with key anatomical landmarks and with the various imaging features of mucoceles of the appendix, in order to provide a meaningful differential diagnosis of a lesion in the right lower abdominal quadrant. In addition, a neoplastic mucocele can rupture, resulting in pseudomyxoma peritonei, which will change the prognosis dramatically. Therefore, prompt diagnostic imaging is crucial.<\/jats:p>","DOI":"10.1590\/0100-3984.2021.0075","type":"journal-article","created":{"date-parts":[[2022,5,2]],"date-time":"2022-05-02T19:55:13Z","timestamp":1651521313000},"page":"193-198","source":"Crossref","is-referenced-by-count":17,"title":["Mucocele of the appendix: what to expect"],"prefix":"10.1590","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8609-2265","authenticated-orcid":false,"given":"Sofia Frade","family":"Santos","sequence":"first","affiliation":[{"name":"Instituto Portugu\u00eas de Oncologia de Lisboa Francisco Gentil (IPOLFG),  Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6834-6225","authenticated-orcid":false,"given":"Mariana","family":"Horta","sequence":"additional","affiliation":[{"name":"Instituto Portugu\u00eas de Oncologia de Lisboa Francisco Gentil (IPOLFG),  Portugal;
