Clear cell adenocarcinoma of the uterine cervix arising from a background of cervical endometriosis.

The radiological findings of cervical clear cell adenocarcinoma (CCA) have not been described previously. Here, we present MR findings of this neoplasm that included mixed solid and cystic components with eccentric solid components. These are similar to the MR features of ovarian CCA. Endometriosis was also noted in the uterine cervix. Coexistence of CCA and endometriosis at the cervix suggests that the pathogenesis may be similar to that of ovarian CCA.
