MRI of rare vaginal tumors: Report of two cases

Abstract

Tumors of the vagina are overall rare and unexplored entities and thus often pose diagnostic dilemmas. We report two rare malignant vaginal tumors and their magnetic resonance imaging (MRI) appearances. We describe two cases of rare vaginal malignancies. In the first case of a 29-year-old married, nulliparous woman, MRI revealed a T2 heterogeneous peripherally enhancing mass involving the upper vagina and the cervix. The uterus was uninvolved. A biopsy was obtained, which showed features of choriocarcinoma. In the second case of a 13-year-old adolescent girl, MRI revealed a T2 hyperintense, moderate to intensely enhancing mass within the vagina. The patient was examined, and tissue sampling was obtained, which showed embryonal rhabdomyosarcoma (RMS). Primary choriocarcinoma and embryonal RMSs of the vagina are extremely rare. Choriocarcinomas are treated by chemotherapy and RMSs by chemotherapy, surgery, and/or radiation therapy. Accurate characterization and staging on imaging help in appropriate intervention.
