MRI classification of uterosacral ligament involvement in endometriosis: the Hôtel-Dieu classification.

Objective: This study aimed to establish the first-ever MRI classification of uterosacral ligament (USL) involvement in deep infiltrating endometriosis (DIE), based on reliable preoperative MRI features correlated with positive predictive values (PPVs) determined through histopathological analysis.

Methods: Twenty-two women underwent surgery with histopathology due to symptoms highly suggestive of endometriosis. The 22 preoperative MRIs were analysed retrospectively, blinded to histopathology, and a classification of the preoperative aspect of USLs linked to PPVs was designed.

Uterine Sarcomas: Are There MRI Signs Predictive of Histopathological Diagnosis? A 50-Patient Case Series with Pathological Correlation.

Purpose: To make clear distinction between two radiological types of uterine sarcomas.

Methods: 50 preoperative MRI were analyzed retrospectively, blinded to histopathology: 11 endometrial stromal sarcomas (ESS), 19 leiomyosarcomas (LMS), 18 carcinosarcomas/malignant mixed Mullerian tumors (MMMT), and 2 smooth muscle tumors of uncertain malignant potential (STUMP).

Results: According to their locations, two radiological types of sarcomas were identified: type 1: intracavitary (ESS, MMMT) and type 2: intramyometrial (LMS, STUMP).

Documentation of normal shape and measurements of the uterine fundus at reproductive age.

Background: The diagnosis of congenital uterine anomalies and the differentiation between different subtypes is based on various sets of measurements that are difficult to implement during daily workflow.

Purpose: To describe the shape and range of measurements of the normal uterus at the fundus in women of reproductive age.

Material And Methods: This retrospective study was conducted on 200 pelvic magnetic resonance imaging (MRI) examinations of female patients of reproductive age with normal uteri divided into three age groups (15-24 years, 25-34 years, 35-45 years).

Auto-amputated adnexa in a young woman: Multimodal imaging to rule in a pelvic rolling stone.

We report the case of a 26-year-old woman with a right auto-amputated adnexa and a free-floating mass in the pouch of Douglas using multimodal imaging studies including ultrasonography, computed tomography, and magnetic resonance imaging. The absence of an ovary and the evidence of an amorphous and potentially calcified mass, with no connection to the genital tract - in particular when it is found to be mobile - are the key imaging findings. Prospective diagnosis of adnexal auto-amputation could assist surgeons in patient management with a curative laparoscopy in symptomatic women, or potentially expectant management in young women who are asymptomatic or have unrelated symptoms.

MRI and CT of sacrocolpopexy.

Objective: The purpose of this article is to describe the surgical procedure of sacrocolpopexy as well as the normal postoperative features and complications on cross-sectional imaging, with an emphasis on MRI.

Conclusion: Sacrocolpopexy with mesh insertion is a commonly performed operation to treat pelvic organ prolapse. MDCT and MRI are used not only to evaluate for potential complications of the procedure but also to evaluate for functional disorders and recurrent prolapse.

In vivo visualization of the levator ani muscle subdivisions using MR fiber tractography with diffusion tensor imaging.

Understanding the levator ani complex architecture is of major clinical relevance. The aim of this study was to determine the feasibility of magnetic resonance (MR) fiber tractography with diffusion tensor imaging (DTI) as a tool for the three-dimensional (3D) representation of normal subdivisions of the levator ani. Ten young nulliparous female volunteers underwent DTI at 1.

A regressive Meigs syndrome after definitive adnexal torsion.

The Meigs syndrome is a rare but well known syndrome in which removal of the tumor results in cure. We report a case of a regressive Meigs syndrome after a definitive adnexal torsion which highlights the major role of the vascular phenomena in the physiopathology of this puzzling syndrome.

Comparison of coronal and axial computed tomography measurements of mediastinal nodes before primary surgery for non-small cell lung cancer.

Objective: To assess computed tomography (CT) evaluation of mediastinal nodes in non-small cell lung cancer to predict metastatic involvement by measurement of their axis and surface area in the coronal plane, as compared to standard short-axis measures in the axial plane.

Methods: Evaluation of mediastinal nodes was retrospectively performed on CT scans of 100 patients before thoracotomy. In all patients, mediastinal dissection was performed in the appropriate stations (n=264) according to the side (59 right, 41 left) of the tumor.

Characterization of papillary projections in benign versus borderline and malignant ovarian masses on conventional and color Doppler ultrasound.

Objective: The purpose of our study was to evaluate on endovaginal ultrasound the morphologic and color Doppler characteristics of papillary projections in benign compared with borderline and malignant epithelial stromal ovarian tumors.

Materials And Methods: A total of 283 women (mean age, 52 years; age range, 20-85 years) with 343 operated adnexal masses comprising 167 epithelial stromal tumors of the ovary with 76 tumors containing papillary projections at pathology were retrospectively studied on ultrasound. We systematically evaluated the topography of the papillary projections, the morphologic features of the largest papillary projection, and the presence or absence of color Doppler findings.

Variable MR findings in ovarian functional hemorrhagic cysts.

Purpose: To describe the magnetic resonance (MR) findings in ovarian functional hemorrhagic cysts (FHC).

Materials And Methods: A total of 21 patients with 22 FHC, proven by follow-up ultrasound (US) in 11 women and surgery in 10 women, had US and MR examinations within 24 hours. The study was limited to cysts with obvious an echogenic pattern.

Vesicouterine fistulas: imaging findings in three cases.

Objective: The objective of our report is to present three cases of vesicouterine fistulas secondary to a cesarean delivery, a uterine rupture during labor, and radiation therapy. The delay between the onset of symptoms and the diagnosis varied between 3 and 7 years. Different techniques such as color Doppler sonography, excretory urography, cystography, CT, MRI, cystoscopy, vaginoscopy, and hysterography were performed with variable results, mostly negative and sometimes undefined.

Adnexal torsion: magnetic resonance findings in the viable adnexa with emphasis on stromal ovarian appearance.

Purpose: To evaluate ultrasound (US) and magnetic resonance (MR) findings in the viable twisted adnexa.

Materials And Methods: Ten patients underwent US and MR studies before surgical detorsion. Corrected cross-sectional area of the ovary was defined as cross-sectional area minus areas of cysts and follicles superior to 1 cm.

Deep pelvic endometriosis: MR imaging for diagnosis and prediction of extension of disease.

Purpose: To prospectively evaluate the accuracy of magnetic resonance (MR) imaging for the preoperative diagnosis of deep pelvic endometriosis and extension of the disease.

Materials And Methods: One hundred ninety-five patients (mean age, 34.2 years; range, 20-71 years) who were suspected of having pelvic endometriosis were recruited at two institutions.
