Gartner's duct cyst with a single vaginal ectopic ureter and associated renal dysplasia or agenesis

Two cases of Gartner's duct cyst with vaginal ectopic ureter and associated renal anomalies are reported. This unusual wolffian duct anomaly may be more common than previously suspected, especially in Asian patients. The radiologist and ultrasonographer should be aware of this anomaly and should perform a pelvic sonogram in any patient in whom there appears to be an absent or dysplastic kidney. Care should be taken to try and identify the Gartner's duct cyst extending caudally posterior to the base of the urinary bladder.
