Recurrent giant Gartner's duct cysts. A report of two cases.
BACKGROUND
Gartner's duct cysts are cystically dilated wolffian duct remnants found in the upper anterolateral part of the vagina. Many such giant cysts are diagnosed during childhood and result from ectopic communication with the ureter or cervix. There is a paucity of literature on recurrent and giant cysts presenting among older women.


METHODS
A 43-year-old woman presented in 1981 with a 7 x 14-cm, left, paravaginal, cystic mass. This was initially drained vaginally, then marsupialized vaginally. Following marsupialization, the patient began to note large gushes of fluid from the vagina. Ultrasound demonstrated a 3-cm cyst thought to arise within the broad ligament. The patient required total abdominal hysterectomy/bilateral salpingo-oophorectomy for endometrial hyperplasia. Exploration revealed neither a broad ligament nor vaginal mass. Postoperatively, vaginal drainage continued. Computed tomography demonstrated a multiloculated, cystic mass left of the vaginal cuff. Exploratory laparotomy revealed the mass to be within the paravaginal space. The cyst was marsupialized into the peritoneal cavity. A 32-year-old woman was diagnosed in 1992 with an 8 x 10-cm right pelvic mass found on examination and confirmed by computed tomography. At exploratory laparotomy the mass was found to be within the paravaginal space and was resected vaginally. In 1999 the patient returned, complaining of rectal pain. Examination and ultrasound revealed a right, multiloculated pelvic mass displacing the rectum, uterus and vagina. Magnetic resonance imaging demonstrated that the mass was entirely inferior to the levator plate. The cyst was resected vaginally.


CONCLUSIONS
Giant Gartner's cysts tend to be misdiagnosed as pelvic masses. Magnetic resonance imaging is the best imaging modality for localizing these cysts. Recurrences of giant cysts tend to be multiloculated. Management strategies for multiloculated recurrences include periodic surveillance, schlerotherapy and marsupialization into the peritoneal cavity.
