Abstract:
HTML

We classified uterine cystic lesions into 3 groups: cystic lesions arising from myometrium, endometrium and cervix. The radiologic findings of each disease are presented with pathologic backgrounds. 1. Myometrial cystic lesion: the most common nontumorous condition is adenomyosis including adenomyotic cyst. The congenital cystic lesions are rare. The most common benign tumorous cystic lesions are degenerated leiomyomas but some other benign mesenchymal tumors can also show cystic feature. Sarcomas such as endometrial stromal sarcoma or leiomyosarcoma contain cystic necrosis or hemorrhage. 2. Endometrial cystic lesion: nontumorous cystic lesions are commonly observed in tamoxifen related endometrial lesion. Trophoblastic neoplasms and non-tumorous placental polyp also consist of cystic component. 3. Cervical cystic lesion: Nabothian cysts are very common cystic condition in the cervix. Adenoma malignum or well-differentiated adenocarcinoma can also show multicystic feature.

 

 

1. To describe the radiologic findings of various cystic lesions in the uterus, including both tumorous and nontumorous condition. 2. To correlate the radiologic findings of uterine cystic lesions with pathologic background.
