T2 hyperintense myometrial tumors: can MRI features differentiate leiomyomas from leiomyosarcomas?

Purpose: To establish MRI features that help differentiate atypical leiomyomas and leiomyomas with degeneration that show hyperintensity on T2WI from leiomyosarcomas.

Methods And Materials: This retrospective study evaluated 41 women who performed MRI before undergoing hysterectomy and had histologically proven atypical leiomyomas, leiomyomas with degeneration or leiomyosarcomas (21 leiomyomas; 20 leiomyosarcomas); only patients with T2 hyperintense myometrial tumors were included. The association between MRI features (contours; free pelvic fluid; intra-tumoral hemorrhagic areas, T2 heterogeneity; T2 dark areas; flow voids; restriction on diffusion-weighted images; signal intensity and heterogeneity after contrast administration; unenhanced areas, localization of unenhanced areas; necrosis; cystic areas) and the histology (leiomyoma vs.

Primary vaginal malignancies: a single oncology centre experience.

Primary vaginal malignancies constitute a rare entity. The aim of this study was to review all primary vaginal malignancies diagnosed in an oncologic referral centre over 11 years. A total of 35 cases were retrospectively analysed, including clinical and MRI features.
