Abstract:

Primary leiomyoma is a rare, benign tumour of the ovary. We describe the MRI features of an ovarian leiomyoma identified in a 51-year-old woman after hysterectomy. The tumour appeared as a well-circumscribed low signal intensity mass on T₁ weighted imaging, with mixed signal intensity on T₂ weighted imaging. Areas of high signal intensity on T₂ weighted imaging corresponded to degeneration of leiomyoma. Dynamic contrast-enhanced imaging revealed early enhancement of the lesion. MRI appearance was thus similar to that of uterine leiomyoma. This case suggests the potential usefulness of dynamic contrast-enhanced MRI for the diagnosis of ovarian leiomyoma.
