“…Theories reported earlier are haematogenic or lymphogenic dissemination of endometriosis cells from the abdominal cavity and metaplasia [ 11 ]. Moreover, spontaneous endometriosis located in the inguinal region is thought to develop from direct extension from pre-existing endometriosis along the round ligament [ 28 ]. This mechanism may also have played a role in our two patients with spontaneous AWE lesions.…”

ObjectiveAbdominal wall endometriosis (AWE) is defined as endometrial tissue that is superficial to the peritoneum. AWE is often difficult to diagnose, mimicking a broad spectrum of diseases. The aim of this study was to describe the appearance of AWE on magnetic resonance (MR) imaging.MethodsWe present ten patients with AWE (12 lesions) in which MR imaging was used for diagnosis. MR imaging included T2-weighted imaging and T1-weighted imaging with fat suppression. To assess the value of diffusion-weighted imaging (DWI) in endometriosis, four patients underwent additional DWI. The apparent diffusion coefficient (ADC) was calculated using b values of 50, 400, 800 and 1,200 s/mm2.ResultsIn most cases, the lesion was located ventral or dorsal to the aponeurosis of the rectus oblique muscle (n = 6) or in the rectus abdominis (n = 5). MR of AWE lesions showed isointense or slightly hyperintense signal compared with muscle on T2-weighted images and showed isointense or slightly hyperintense signal compared with muscle on T1-weighted images with foci of high signal intensity, indicative of haemorrhage. The mean ADC value of AWE was 0.93 × 10–3/mm2/s.ConclusionMR imaging seems to be useful in determining the location and depth of infiltration in surrounding tissue preoperatively.

“…Some studies use the value of 9 mm for uterosacral ligament thickness to define involvement. Bazot et al and Jarlot et al used rather irregularity and asymmetry of uterosacral ligaments to define their involvement because they observed that ligaments measuring less than 9 mm may be involved (Figure 4) [5, 11, 13, 35]. Posterior cul-de-sac lesions include retroperitoneal lesions and intraperitoneal infiltrating lesions, which are divided into rectovaginal septum lesions (type I), posterior wall forniceal lesions (type II), and hourglass shaped lesions (type III).…”

MR imaging is becoming increasingly important in the assessment of patients with endometriosis. Its multiplanar capabilities and superior soft tissue contrast are particularly useful in the detection of deep infiltrating endometriotic implants. Endometriosis, defined as the presence of endometrial glands and stroma outside the endometrium, is among the most common gynaecological disorders affecting women in their reproductive age. The diagnosis and evaluation of the extension of endometriosis are difficult only with physical examination and laparoscopy. According to the authors' personal experience, a special MRI technique and some imaging guidelines regarding different anatomical localizations of endometriosis are discussed. This review is a brief presentation of current evidence on the diagnostic accuracy of MRI in the evaluation of endometriosis concerning other diagnostic methods, the limitations of MRI and its essential usefulness for preoperative diagnosis of deep pelvic endometriosis, and future perspectives in monitoring this disease.

“…CA 125 level was normal in our case. US and CT are not diagnostic; however, US features of mixed echogenicity and lack of blood flow can be suggestive while CT helps define anatomy and proximity to vessels 4. Treatment options include expectant management, hormonal therapy or complete surgical excision with avoidance of spillage to prevent recurrence 3.…”
