Mucoceles of the appendix are rare and can have quite variable imaging and clinical presentations, sometimes mimicking an adnexal mass. 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.
阑尾黏液囊肿罕见，其影像学表现和临床表现差异很大，有时可酷似附件肿物。其潜在病因可为肿瘤性或非肿瘤性。阑尾黏液囊肿典型的影像学表现为具有管状形态的囊性结构。该结构的特点为盲端且与盲肠相连。放射科医生应熟悉关键的解剖标志以及阑尾黏液囊肿的各种影像学特征，以便对右下象限病变进行有意义的鉴别诊断。此外，肿瘤性黏液囊肿可破裂，导致腹膜假黏液瘤，这将显著改变预后。因此，及时的诊断性影像学检查至关重要。
