MRI atlas of ectopic endometriosis.

Ectopic endometriosis is a common condition which is often underdiagnosed, where MRI can help make a diagnosis simply, non-invasively and without irradiation. However, imagery signs of it are enormously polymorphic with a wide range of possible locations. In this paper, we have tried to illustrate comprehensively all its MRI appearances depending on the different locations where it occurs.

[Laparoscopic colorectal resection for deep pelvic endometriosis: Evaluation of post-operative outcome]. / Résections rectosigmoïdiennes cœlioscopiques pour endométriose digestive : résultats chirurgicaux et fonctionnels.

OBJECTIVES: Evaluation of mid-term functional results and the quality of life after laparoscopic colorectal resection. PATIENTS AND METHODS: Twenty-three consecutive patients were included in a retrospective monocentric study. Postoperative functional outcomes and quality of life were analyzed. RESULTS: The median follow-up after colorectal resection was of 24±15.7 months (6-72). Major complications occurred in three cases (12,9%) including one anastomotic stenosis, one digestive and one bladder fistula. A significant improvement in pelvic pain symptoms was observed. De novo constipation and pain on defecation occurred in respectively 23% and 42% of the cases. Transient de novo dysuria occurred in 18% of the cases. The quality of life has been significantly improved. CONCLUSION: Laparoscopic colorectal resection is associated with unfavourable postoperative digestive and urological outcomes, such as bladder and rectal dysfunction. Radical treatment should be limited to selected patients.

[MRI in static and dynamic disfunction of the female floor]. / Troubles de la statique et de la dynamique pelvienne chez la femme en IRM.

MRI is taking a growing place for pelvic prolapse diagnosis. A strict technical protocol with static and dynamic sequences is required with rectal and vaginal ultrasound gel. A good knowledge of physiology and anatomy of pelvic and perineal muscles is mandatory as well as a clinical approach of various pathologic prolapses. MRI fundings are presented and correlated with several clinical situations of prolapse and post operative features.

[Imaging of female infertility]. / Imagerie de l'infertilité féminine.

Medical treatment of a couple's infertility depends upon the cause(s) of infertility. The goals of imaging are to determine these causes (male, female, mixed, unexplained), to evaluate their severity and type on the female side central, ovarian, uterine, tubal, peritoneal, endometriosis, in order to propose an adapted treatment. Imaging modalities are essentially non ionising (US and MRI). Hysterosalpingogram retains its indication to study tubal patency, it can be completed by tubal catheterisation in cases of proximal tubal obstruction.

[Acquired uterine arteriovenous fistula: report of one case]. / Fistule artério-veineuse utérine acquise: à propos d'une observation.

A case of acquired uterine arteriovenous fistula in a 28 Year old patient is reported that probably is secondary to a "difficult" delivery. Sono-graphic, MRI and angiographic findings are reported, before and after endovascular management.

Magnetic resonance imaging of the pelvic floor.

Magnetic resonance imaging is a novel noninvasive imaging modality for the assessment of pelvic floor dysfunction. It relies on static sequences with a high spatial resolution to study muscle morphology (levator ani) and fast imaging dynamic sequences during contraction, rest, and straining. Prolapse of the various pelvic compartments is detected with respect to organ position relative to the pubococcygeal line during dynamic phases. Compared with clinical examination, its input appears to be especially invaluable in the posterior compartments (peritoneal and digestive) and to assess complex prolapses involving more than one pelvic compartment. It is also useful for understanding postsurgical recurrences.

High signals in the uterine cervix on T2-weighted MRI sequences.

The aim of this pictorial review was to illustrate the normal cervix appearance on T2-weighted images, and give a review of common or less common disorders of the uterine cervix that appear as high signal intensity lesions on T2-weighted sequences. Numerous aetiologies dominated by cervical cancer are reviewed and discussed. This gamut is obviously incomplete; however, radiologists who perform MR women's imaging should perform T2-weighted sequences in the sagittal plane regardless of the indication for pelvic MR. Those sequences will diagnose some previously unknown cervical cancers as well as many other unknown cervical or uterine lesions.

[A case of muscular and canal of nuck involvement by endometriosis]. / Un cas de localisation d'endométriose musculaire et du canal de nuck.

Endometriosis is defined by the presence of endometrial tissue outside the uterine cavity and having the functional property of menstrual bleeding. We report a case of endometriosis involving the abdominal wall muscles and canal of Nuck in a 28 year old woman. Abdominal wall sonography showed a hypoechoic lesion at the rectus abdominis insertion. T1W and T2W MRI images showed a hemorrhagic high signal intensity lesion in the muscle. MRI also showed a similar lesion in the canal of Nuck.

Imaging of membranous dysmenorrhea.

Membranous dysmenorrhea is an unusual clinical entity. It is characterized by the expulsion of huge fragments of endometrium during the menses, favored by hormonal abnormality or drug intake. This report describes a case with clinical, US, and MRI findings before the expulsion. Differential diagnoses are discussed.

Interventional radiology in female infertility: technique and role.

The purpose of this paper is to describe the modifications in the radiologic approach to female infertility. The role of hysterosalpingography (HSG) has evolved from being the only source of information about the uterus to a more minor role, after ultrasound, that essentially deals with the morphology of the fallopian tubes. But if its diagnostic yield in the uterus is challenged by ultrasound and hysterosonography, it retains a major impact in the work-up of female infertility. Hysterosalpingography brings decisive diagnostic information concerning the state of the tubes and peritoneum. The interventional procedures of selective salpingography and tubal recanalization have a definite therapeutic effect and allow numerous pregnancies that would otherwise have required in vitro fertilization or tubal microsurgery.

[Imaging of gynecologic malformations]. / Imagerie des malformations gynécologiques.

Female genital tract anomalies are common (1 to 2% of the female population), and may lead to multiple clinical manifestations: amenorrhea, infertility, spontaneous repeated miscarriage, pelvic pain, endometriosis. They are caused by intra-uterine insults between weeks 6 and 18 of gestation. They are classified according to their embryologic origin. Imaging relies essentially on ultrasound and MRI, and indications for hysterosalpingography are less common. Imaging must classify the malformation and detect complications in order to assess the fertility prognosis and treat complications.

[Imaging of the cervix and the vagina]. / Imagerie du col et du vagin.

US and MRI currently are the best imaging modalities to evaluate pathology of the uterine cervix and vagina. Carcinoma of the cervix is the most frequent indication for imaging. MRI allows preoperative staging of cervical carcinoma based on FIGO classification, and post treatment follow-up. Other uterine cervix diseases are less frequently imaged and include a wide range of entities that most frequently cause increased T2W signal at MR imaging. Pathology of the pelvic floor, vagina, vulva, and perineum also includes a wide range of entities that have seldom been described in the imaging literature.

[Tubal diseases: from diagnosis to intervention]. / Pathologie tubaire: du diagnostic à l'interventionnel.

Ninety years after it was first performed, hysterosalpingography remains one of the most important tests in helping an infertile couple decide between numerous treatment options. The application of angiographic techniques to hysterosalpingography has revolutionized diagnosis and treatment of proximal tubal obstruction. Results from worldwide centers have shown that nonsurgical catheter recanalization of proximally obstructed tubes can be accomplished in up to 90% of patients using standard techniques. Pregnancy incidence in a population who was recommended for tubal microsurgery or in vitro fertilization, but who underwent catheter tubal recanalization instead without any other therapy, was 58% at one year and all pregnancies were intrauterine. Fluoroscopic fallopian tube catheterization should be the first treatment for proximal tubal obstruction, with the more expensive and invasive procedures reserved for the small number of women who fail the radiologic procedure.
