The Vaginal and perivaginal cysts include
1. Vaginal Cysts
a) Gartner Duct Cysts
b) Bartholin Gland Cysts
2. Perivaginal Cysts
a) Skene Gland Cysts (Periurethral gland Cysts)
b) Nabothian Cysts of Cervix.
Gartner Duct Cysts
'Gartner duct cysts result from incomplete regression of the wolffian ducts. These cysts most commonly develop in the anterolateral wall of the upper vagina, above the inferior border of the pubic symphysis. Gartner duct cysts are lined with nonmucinous cuboidal or columnar epithelium. When Gartner duct cysts are located at the level of the urethra, they can cause mass effect on the urethra, giving rise to urinary tract symptoms.'
(Ref - Overlooked Diseases of the Vagina: A Directed Anatomic-Pathologic Approach for Imaging Assessment October 2011 RadioGraphics, 31, 1583-1598.)
Gartner Duct Cysts as mentioned occur on the upper anterolateral vagina, whereas Batholin Gland Cysts occur in the posterolateral aspect of the lower vagina.Bartholin Cyst's location at or below the level of the pubic symphysis helps to differentiate them from Gartner duct cysts.
As name suggests the Peri-urethral gland(Skene Gland) cysts do occur in the lower periurethral region, anterior to the vagina.The Skene glands are paired structures located near the external urethral meatus, with ducts draining directly into the urethral lumen.
Urethral diverticula, which comes as a DD for Skene Gland Cyst tend to be midurethral in location
