Vaginal metastasis from uterine leiomyosarcoma. Magnetic resonance imaging features with pathological correlation.

Vaginal metastases, though more frequent than primary vaginal tumors, are rare. Except for isolated reports of metastatic disease arising from extragenital organs, the vagina is typically a site for metastatic disease from genitourinary tract sites, especially cervix, endometrium, and kidney. We present herein a case of a 68-year-old woman presenting with a vaginal metastasis as the first manifestation of a uterine leiomyosarcoma. The magnetic resonance imaging features are described and correlated with the pathological findings. To the best of our knowledge, this is the first case of vaginal metastasis from uterine leiomyosarcoma described in the literature.
