2- Review FIGO classification of uterine fibroids.
3- Illustrate the various radiological aspects of uterine myomas,
studying selected cases of MRI.
also known as leiomyomas,
are the most common uterine tumors in women of childbearing age,
and occur in approximately 50% of patients over the age of 40.
they can be associated with significant morbidity,
and present a frequent indication for hysterectomy,
especially in case of recurrent menorrhagia.
Most leiomyomas are asymptomatic,
howerver they may cause abnormal uterine bleeding,
or a palpable abdominopelvic mass.
Their management remains critical,
since it is dealing with young patients of childbearing age,
Findings and procedure details
Reminder of the radiological anatomy of the uterine cavity:
Uterus occupies a medial and subperitoneal position in the female pelvis,
just behind the bladder and in front of the rectum.
It is a fibromuscular organ,
divided into three main anatomic segments (from superior to inferior): the fundus,
and cervix(extends into the vagina).
Several ligaments support the uterine cavity,
including the utero-ovarian ligament,
the broad ligament,
the cardinal ligament and the uterosacral ligament. Fig. 1
The broad ligament of...
Currently, MRI is the preferred imaging modality for uterine fibroids characterization thanks to its morphological and dynamic studies (Enhancement and Diffusion-MRI (DWI)).
It provides a detailed mapping of uterine leiomyomas,
predicts malignancy and atypia signs.
it has an essential place,
guiding the therapeutic management.
