“…Many women experience a considerable delay between the onset of the first symptom and the surgical diagnosis of endometrioma (1), highlighting the importance of developing new, non-invasive techniques to accurately diagnose pelvic endometriotic lesions before surgery. Pelvic MRI has played a major role in the preoperative detection of endometriotic cysts, endometriotic implants, deep pelvic endometriosis, and malignant neoplasms arising from endometrioma (5,11). The MRI features of endometriotic cysts are complex and changeable because the cysts undergo periodic bleeding and fibrosis.…”

“…The diverse symptomatology and reliance on laparoscopy (an invasive procedure) as a goldstandard diagnostic technique result in many women being misdiagnosed and experiencing delays in the range of 4-11 years from first onset of symptoms to surgical diagnosis (1). At present, the commonly used non-invasive methods to diagnose endometrioma include ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) (5)(6)(7)(8)(9)(10). MRI can display endometrioma lesions well, especially those with deep infiltration, and has been used widely as a preoperative investigation (6,11,12).…”

“…MRI has proven to be an effective modality for the preoperative evaluation of diseases of the pelvis, including endometriotic cysts and ectopic pregnancy (3,5,(10)(11)(12)(13)(14)(15). Advances in MRI technology, such as the development of susceptibility-weighted imaging (SWI), have improved the ability of MRI to assess various diseases, especially hemorrhagic infiltrating lesions (16,17).…”

Background Endometrioma is a common manifestation of endometriosis that can be difficult to diagnose with conventional magnetic resonance imaging (MRI). Susceptibility-weighted imaging (SWI) may be more sensitive than conventional MRI in the detection of chronic, local hemorrhagic disease. Purpose To investigate whether signal voids in SWI sequences could be used in the preoperative diagnosis of endometrioma. Material and Methods This retrospective study included consecutive female patients with clinically suspected endometrioma. All patients underwent pelvic 3-T MRI (T1- and T2-weighted) and SWI within two weeks before laparoscopy. Two experienced radiologists blinded to the histopathologic/clinical diagnoses interpreted the images together, and any disagreements were resolved by consensus. Results The final analysis included 73 patients: 46 patients (mean age=37 years; age range=22–68 years) with 85 endometrioma lesions and 27 patients (mean age=34 years; age range=15–68 years) with 34 non-endometrioid cystic lesions (18 hemorrhagic corpus luteal cysts, three simple cysts, three mucinous cystadenomas, two mature teratomas, and one endometrioid cyst with corpus luteum rupture/hemorrhage). The presenting symptoms for patients with endometrioma were chronic pelvic pain (44.6%), dysmenorrhea (31.9%), infertility (12.8%), dyspareunia (6.4%), and menstrual irregularity (4.3%). MRI identified all 119 lesions observed laparoscopically. SWI visualized punctate or curvilinear signal voids along the cyst wall or within the lesion in 67 of 85 endometriomas (78.8%) and only 3 of 31 non-endometrioid cysts (8.8%). Conclusion The use of SWI to look for signal voids in the cyst wall or within the lesion could facilitate the preoperative diagnosis of endometrioma.

“…Post-operative MRI can be useful both to document the success of the surgery with normal post-operative findings and to highlight some paraphysiological conditions such as the presence of fibrosis, adhesions or even alterations of the pelvic anatomy that can contribute to symptoms or disorders. It is also possible that a CT scan or MRI may be necessary to assess post-operative complications or the presence of recurring or residual disease [89].…”

Endometriosis is a chronic condition characterized by the presence of abnormal endometrial tissue outside the uterus. These misplaced cells are responsible for inflammation, symptoms, scar tissue and adhesions. Endometriosis manifests mainly in three patterns: superficial peritoneal lesions (SUP), ovarian endometriomas (OMA) and deep infiltrating endometriosis (DIE). It also exhibits atypical and extremely rare localization. The updated 2022 guidelines of the ESHRE recommend using both ultrasound and magnetic resonance imaging (MRI) as first-line diagnostic tests. Currently, MRI provides a more complete view of the pelvis anatomy. The aim of our review is to provide radiologists with a “map” that can help them in reporting pelvic MRI scans in patients with endometriosis. We will illustrate the usual and unusual localizations of endometriosis (categorized into compartments) using post-operative imaging, and we will focus on the role of MRI, the main sequences and the use of contrast agents.
