There several cystic lesions around the vagina and female urethra; some of the imaging differential considerations would include:
- urethral diverticulum
- Gartner duct cyst: at or above the level of the pubic symphysis anterior to the vaginal wall
- Bartholin gland cyst: posterolateral to distal vaginal wall inferior to the symphysis pubis
- Bartholin gland tumor: consider if discovered in the postmenopausal patient
- Bartholin gland abscess
- Skene duct cyst: centered anterior to the distal portion of the urethra close to the external urethral meatus
- Nabothian cyst: located at a much higher position within the uterine cervix
- adenoma malignum of the cervix extending to upper vagina
- canal of Nuck hydrocele
mucus cysts of vagina: in proximal vagina; derived from Mullerian duct
