Abstract

We report a case of vaginal leiomyoma in a female patient, which presented with a palpable paraurethral mass with several urinary symptoms such as frequency, urgency and dysuria. The physical examination revealed a localized, mobile, nontender mass in the anterior vaginal wall. Pelvic magnetic resonance (MR) imaging showed a malignant-looking vaginal mass co-existing with multiple uterine leiomyomas. The diagnosis was made through transvaginal ultrasound-guided needle biopsy. The surgical excision was accomplished without any complication. Despite the rarity, a few cases of malignant lesion presented with paraurethral mass were previously reported. The surgical excision and pathological confirmation of the benignancy is necessary.

Key Words: Vaginal leiomyoma, Paraurethral mass, MR imaging
