Abstract:

Pseudoneoplastic glandular lesions are benign lesions that are often histologically and radiographically confused with adenoma malignum, which is a rare variant of mucinous adenocarcinoma of the uterine cervix. 15 cases of pseudoneoplastic glandular lesions, characterized by multilocular cystic masses in the uterine cervix, were investigated; these lesions included endocervical glandular hyperplasia, deep nabothian cysts and tunnel cluster. All lesions were proven by conization or hysterectomy. The MR findings correlated closely to the histopathological specimens. As a result, MR findings of pseudoneoplastic glandular lesions were almost identical to those of adenoma malignum; hence, it was almost impossible to differentiate between the two pathologies. Radiologists should be aware that these two conditions are quite similar in morphology.
