RESUMO
BACKGROUND: Gartner duct cysts develop from mesonephric duct remnants. They are usually small and asymptomatic, but complications can arise and are uncommonly reported. CASE: A 44-year-old patient presented with acute pelvic pain and pressure, a new vaginal mass, and urinary retention. Examination and magnetic resonance imaging revealed a large, expanding, complex paravaginal mass with extension into the paracervical and ischiorectal spaces, causing cephalad displacement of the uterus. A vaginal approach to cyst incision, hemorrhage control, and marsupialization resulted in complete resolution of symptoms. Pathology demonstrated a Gartner duct cyst without evidence of malignancy. CONCLUSION: Spontaneous hemorrhage of a Gartner duct cyst, although rare, may cause acute symptoms and a new vaginal mass. This diagnosis should be considered in the evaluation of acute-onset pelvic pressure and pain.
