“…Regarding the diagnosis of bladder endometriosis, the present study reported similar values of sensitivity and specificity of MRI (67% and 100%) to those described by others authors . Furthermore, the present study showed that MRI had good concordance (Cohen's kappa test: 0.77) with surgery and reliable likelihood ratios (LR+ infinitive, LR− 0.3) for bladder location of DIE.…”

Objective: To compare the performance of magnetic resonance imaging (MRI) and transvaginal ultrasound (TVU) in detecting deep infiltrating endometriosis (DIE), using Enzian classification. Secondarily, to evaluate the influence of nodule size on the accuracy of MRI and TVU. Methods: A retrospective study was carried out at "La Paz" University Hospital, Madrid, Spain, between April 2012 and December 2014. Inclusion criteria were suspicion of DIE at gynecologic examination, indication to undergo TVU, MRI and surgery. Exclusion criteria were previous hysterectomy, bowel resection, or urinary tract surgery. The diagnosis of DIE using MRI or TVU was considered positive when it correlated with histology.Sensitivity, specificity, accuracy, and mean size of the nodule were calculated. Results:In the present study involving 48 women, TVU demonstrated greater accuracy than MRI for recto-vaginal (77% vs 69%) and vaginal (94% vs 89%) endometriosis. MRI showed greater accuracy (96%) than TVU (92%) for bladder endometriosis. The size of the nodule did not have a significantly different effect on the accuracy of TVU compared with MRI. Conclusion:In the present study, TVU provided a more accurate localization of vaginal and recto-vaginal endometriosis as compared with MRI; however, MRI should be recommended if a suspicion of bladder endometriosis exists. The nodule size did not seem to influence the accuracy of the two techniques.

“…Although we did not perform magnetic resonance imaging (MRI) in the present two patients, MRI is proving increasingly used for the detection and diagnosis of endometriosis. The sensitivity of MRI for the evaluation of endometriosis is reportedly 69%-92%, and the specificity is 75%-98% (16)(17)(18)(19). Endometriotic lesions typically show low to intermediate signal intensity on T1-and T2-weighted imaging.…”

We herein report two patients with endometriosis in the cecum. Both patients presented with a protruding, subepithelial tumor on colonoscopy and were diagnosed with cecal endometriosis after surgical resection. It is notable that the cecal lesions were not initially identified on computed tomography (CT), while CT colonography with air/carbon dioxide insufflation resulted in the detection of the cecal tumor. These cases highlight the possibility of false-negative results on conventional CT in patients with cecal endometriosis. We consider CT colonography with air/carbon dioxide insufflation useful for detecting cecal tumors in such cases.

“…Magnetic resonance imaging (MRI) is increasingly being used in the evaluation of patients with endometriosis, as a complementary method to transvaginal ultrasonography [ 76 ], particularly when the clinician questions the possible presence of deep infiltrative lesions. Other situations where MRI is useful, include the cases in which the sonographic features are elusive, or when surgery is programmed, as it provides a greater contrast resolution and a larger field of view compared to ultrasound [ 77 ]. The spectrum of endometriotic lesions which can be observed during an MRI examination is variated, some of the main lesion types being represented by superficial peritoneal implants, adhesions, endometrial ovarian cysts, and deep infiltrating endometriosis involving round ligaments, retro cervical region, the bladder or rectal wall [ 78 ].…”

Endometriosis Associated Infertility: A Critical Review and Analysis on Etiopathogenesis and Therapeutic Approaches

Endometriosis represents a frequently diagnosed gynecological affliction in the reproductive timespan of women, defined by symptoms ranging from pelvic pain to infertility. A complex interplay between the genetic profile, hormonal activity, menstrual cyclicity, inflammation status, and immunological factors define the phenotypic presentation of endometriosis. To date, imaging techniques represent the gold standard in diagnosing endometriosis, of which transvaginal ultrasonography and magnetic resonance imaging bring the most value to the diagnostic step. Current medical treatment options for endometriosis-associated infertility focus on either stimulating the follicular development and ovulation or on inhibiting the growth and development of endometriotic lesions. Techniques of assisted reproduction consisting of superovulation with in vitro fertilization or intrauterine insemination represent effective treatment alternatives that improve fertility in patients suffering from endometriosis. Emerging therapies such as the usage of antioxidant molecules and stem cells still need future research to prove the therapeutic efficacy in this pathology.
