A pre-operative diagnosis of minimal deviation adenocarcinoma of the cervix is often difficult. We assessed transvaginal sonography, computed tomography and magnetic resonance imaging in 16 women with histologically confirmed minimal deviation adenocarcinoma. Increased fluid accumulation was frequently observed within the endometrial cavity and/or vagina by all three techniques. A multicystic cervical lesion was occasionally detected by transvaginal sonography or by computed tomography. On T2-weighted magnetic resonance images, a noncystic fine villous or multicystic lesion was noted in most cases. Among the three imaging techniques used, T2-weighted magnetic resonance images showed the most detailed features and the best correlation with the histology.
