Vaginal leiomyoma. A case report with imaging findings.

BACKGROUND: Vaginal leiomyoma is a rare tumor with a variable clinical presentation. The imaging features have not been described previously. CASE: A 42-year-old nulligravida presented with a vaginal mass. Ultrasound demonstrated a solid, rather than cystic, mass. Magnetic resonance imaging (MRI) showed a homogeneous lesion with a signal similar to that of the myometrium. Excision of a benign vaginal leiomyoma was performed without difficulty. CONCLUSION: Vaginal leiomyoma presenting as a mass is most often diagnosed clinically and readily treated at surgery. An uncommon presentation may necessitate imaging studies. The lesion described had MRI and ultrasound features similar to its uterine counterpart.
