Gartner’s duct cyst is a benign cystic lesion arising from persistent remnants of the mesonephric (Wolffian) duct in females. It is most commonly located along the anterolateral vaginal wall and is often detected incidentally. Presentation in the posterolateral aspect of the rectovaginal pouch is uncommon. We report the case of a 32-year-old multiparous woman who presented with chronic vaginal discharge and pelvic discomfort and was found to have a Gartner’s duct cyst located in the left posterolateral rectovaginal pouch, extending superiorly to the posterior lip of the cervix. Radiological evaluation with ultrasound and MRI suggested a benign cystic lesion, and histopathological examination confirmed the diagnosis. This case highlights an unusual anatomical location of a Gartner’s duct cyst and underscores the importance of considering it in the differential diagnosis of posterior vaginal and rectovaginal cystic lesions.
