Avoiding treatment of leiomyosarcomas: the role of magnetic resonance in focused ultrasound surgery

The possibility of inadvertent treatment of malignant disease and thus delayed diagnosis exists with all non-excisional therapies for uterine leiomyomas. The pretreatment imaging before MRgFUS in this case led to an expedited diagnosis of malignancy. Although this did not lead to a change in prognosis for this patient, careful review of magnetic resonance imaging before MRgFUS may allow early diagnosis for uterine malignancies.
