Learning objectives

1.Remind the new FIGO classification of uterine leiomyomas. 2.Describe different radiological appearances of myomas according to their histological subtypes or form of degeneration. 3.Understand MR imaging features that allows ruling out differential diagnosis.

Background

Leiomyoma is the most frequent pelvic benign neoplasm affecting approximately 30% of women in reproductive age. Most fibroids are asymptomatic, but patient may present with abnormal uterine bleeding or bulk-related symptoms requiring a surgical treatment. Ultrasonography is still the first diagnostic test for patients with fibroids, but can provide insufficient results. Magnetic resonance Imaging (MRI) is the most accurate imaging modality for detection, mapping and characterization of leiomyomas and their mimics. It helps referring patients to the most appropriate therapy and has become the most...

Findings and procedure details

Pelvic MRI is the most effective imaging method for detection, localization and characterization of leiomyomas. 1. Localization of leiomyomas: *Single or multiple fibroids and their size: number and size of leiomyomas must be indicated to attempt conservative treatment *Part of the uterus involved by the myoma :uterine corpus, fundus or the cervix *Anterior, posterior or lateral localization of myoma *Depth localization in myometrium according to the new FIGO classification *Relationship with neighboring structures FIGO classification of myomas (2011): Fig.1 Traditionally, myomas were classified as follows:...

Conclusion

MRI is the most accurate imaging modality for detection, mapping and characterization of leiomyomas and provides the key points for adequate management of uterine fibroids
