Imagerie de l'adénomyose

Adenomyosis is a frequent gynecological disorder that affects women above 40 years of age and is responsible for nonspecific symptoms. Imaging is required to establish the diagnosis, the extension of the disease and to rule out other associated diseases. Transvaginal ultrasound is the initial imaging modality. The reported sensibility and specificity vary between 50-89 % and 53-89 % respectively, depending on the coexistence of other disorders. Pelvic MRI can be proposed in case of doubtful diagnosis, with a high sensitivity (78-89 %) and specificity (67-93 %). The most important distinction must be made with leiomyoma. Specific ultrasound and MRI signs have to be sought to correct the diagnosis since therapeutic strategies differ, especially among patients who wish pregnancy.
