Presentation of cases based on our experience. -Check the appearance of endometriosis in atypical clinical contexts and give clues to recognize them.

and materials Endometriosis is the presence of ectopic endometrial tissue outside the uterus. It is a frequent cause of pelvic pain and infertility, which affects 10% of pre-menopausal women. There are 3 forms of endometriosis: -Surface peritoneal lesions -Ovarian endometrioma - Deep pelvic endometriosis: It is located at least 5mm from the peritoneal surface. It is the form that most contributes to pelvic pain and infertility. The imaging test of choice for the correct assessment of this pathology is MRI. It comprises a broad spectrum of radiological...

Radiological semiology -Anexial endometriosis: The ovary is the most frequent location of endometriosis. The most typical finding is the presence of endometriomas. These are cystic lesions that contain products of blood degradation, secondary to cyclic bleeding of the endometrial tissue. The typical semiology of endometrioma is that of a hyperintense lesion in T1 sequences with fat suppression, which loses signal in T2 sequences due to the high content of products of blood degradation. Phenomenon called "shading" (Figure 1). They are usually multiple. The association with...

The radiologist must knows their typical / atypical radiological manifestations of endometriosis, that allow an early diagnosis. MRI is the imaging test of choice. It is essential to include T1 sequences with fat suppression in the RM protocol. A condition that deserves separate mention is the endometriosis associated with hormonal changes in pregnancy or decidual endometriosis. The knowledge of the different radiological forms of pelvic endometriosis is crucial for a correct differential diagnosis and for the orientation of the therapeutic attitude.
