Diagnosis and management of vaginal mullerian cyst in a virgin patient.
Benign cystic lesions of the vagina are uncommon and may become symptomatic. We describe two symptomatic anterior vaginal wall cysts in a virgin patient and the usefulness of imaging modalities. A 36-year-old virgin woman presented with a complaint of vaginal bulging and pelvic pressure. Pelvic examination revealed a cystic mass protruding from the vagina surrounded by the intact hymen. The initial abdominopelvic ultrasound showed a hypoechoic cystic mass measuring 42 x 20 mm in the vagina. She then had a pelvic magnetic resonance imaging (MRI) that revealed two anterior vaginal wall cysts with no communication with the urethra or bladder. The cysts were excised and histologic examination with mucicarmine revealed mucin-secreting tall columnar cells consistent with a diagnosis of mullerian cyst. While both ultrasonographic examination and MRI are helpful in localizing vaginal cysts, MRI is superior in showing multiple cystic lesions of the vagina and their communication with the surrounding structures.
