Adenoma malignum: MR imaging and pathologic study.

MR Imaging features of pelvic mucinous carcinomas

“…8) [12]. The lesions appear isointense or slightly hyperintense relative to the uterus on T1-and m a r k e d l y hyperintense relative to the uterus on T2-weighted M R images [4]. The high T2 signal intensity of a d e n o m a m a l i g n u m m a y be similar to those of N a b o t h i a n cysts, although the f o r m e r contains solid neoplastic tissue which shows e n h a n c e m e n t after injection of g a d o f i n i u m -D T P A (Fig.…”

“…These factors may lead to a poorer prognosis in patients with the mucinous as compared with non-mucinous carcinomas. Because of the ext_racellular mucin, mucinous carcinomas t~q3ically show predominantly a very high signal intensity on 2"2-weighted MR images, and therefore may resemble numerous other malignant or benign conditions such as necrotic tumors, fluid collections, cysts, and liver hemangiomas [3,4]. To familiarize the readers with the MR imaging appearance, and to prevent some of the pitfalls, this paper illustrates the MR imaging features of pelvic mucinous carcinomas.…”

Radiological features of adenoid cystic carcinoma of the uterine cervix

“…Several tumors or tumor-like lesions, including adenocarcinoma, adenoma malignum, nabothian cysts and florid endocervical glandular hyperplasia, also show very high-signal intensity on T2-weighted MR images and should be considered in the differential diagnosis [8][9][10]. Adenoma malignum is characterized as a multicystic lesion with or without some solid components in the deep cervical stroma.…”

“…Adenoma malignum is characterized as a multicystic lesion with or without some solid components in the deep cervical stroma. The majority of cysts are less than 10 mm in the largest diameter [10] and show characteristic symptoms of watery discharge. Adenoma malignum is often associated with Peuts-Jeghers syndrome.…”

Cystic lesions of the female reproductive system: a review

“…While follicles and the dominant follicle are anechoic and thin walled, corpus luteum is typicalentities with adenoma malignum, a rare minimally invasive adenocarcinoma, is occasionally difficult (7). Besides a watery discharge, which is the most common initial symptom of adenoma malignum, solid components in the deep cervical stroma with enhancement in a complex multicystic mass filling the endocervical channel are suspicious of adenoma malignum (7,8).…”
