Mesonephric and Paramesonephric Cysts

33year old female whose LMP was 3 weeks ago. USscan scan shows three cystic areas in the lower uterine segment (yellow overlay) likely representing mesonephric and paramesonephric cysts, and a cervical cyst likely representing a nabothian cyst.(orange) Differential diagnoses of cystic uterine lesions include cystic degeneration of uterine leiomyoma, cystic adenomyosis (adenomyotic cysts), congenital uterine cysts such as mesonephric and paramesonephric cysts, cervical nabothian cysts,

intramyometrial hydrosalpinx, and echinococcal cysts. nabothian cysts classically related to the cervix often associated with chronic cervicitis. paramesonephric or mesonephric cysts. unusual, benign congenital anomalies. not typically associated with other GU anomalies likely incidental usually followed over time rare cases of malignancy arisenin walls of these cysts. uterus lower uterine segment cysts nabothian mesonephric cyst paramesonephric cyst USscan ultrasound Courtesy Ashley Davidoff copyright 2009 all rights reserved 85453c01.8s

Mesonephric and Paramesonephric Cysts



33year old female whose LMP was 3 weeks ago. USscan scan shows three cystic areas in the lower uterine segment (yellow overlay) likely representing mesonephric and paramesonephric cysts, and a cervical cyst likely representing a nabothian cyst.(orange) Differential diagnoses of cystic uterine lesions include cystic degeneration of uterine leiomyoma, cystic adenomyosis (adenomyotic cysts), congenital uterine cysts such as mesonephric and paramesonephric cysts, cervical nabothian cysts,
 
intramyometrial hydrosalpinx, and echinococcal cysts. nabothian cysts classically related to the cervix often associated with chronic cervicitis. paramesonephric or mesonephric cysts. unusual, benign congenital anomalies. not typically associated with other GU anomalies likely incidental usually followed over time rare cases of malignancy arisenin walls of these cysts. uterus lower uterine segment cysts nabothian mesonephric cyst paramesonephric cyst USscan ultrasound Courtesy Ashley Davidoff copyright 2009 all rights reserved 85453c01.8s
