Gartner's duct cyst

A Gartner's duct cyst (sometimes incorrectly referred to as vaginal inclusion cyst) is a benign vaginal cystic lesion that arises from the vestigial remnant of a mesonephric duct (wolffian duct)or Gartner's duct. They are typically small asymptomatic cysts that occur along the lateral walls of the vagina, following the course of the duct. They can, however, enlarge to substantial proportions and be mistaken for urethral diverticulum or other structures.

There is a small association between Gartner's duct cysts and metanephric urinary anomalies, such as ectopic ureter & ipsilateral renal hypoplasia.
