RESUMO
BACKGROUND: Lipomodelling (LM) is an increasingly used technique to reconstruct or correct an aesthetic defect linked to a loss of substance. In France, the Haute Autorité de santé (HAS) published recommendations in 2015 and 2020 concerning the conditions of use of LM on the treated and contralateral breast. These appear to be inconsistently followed. METHODS: Twelve members of the Senology Commission of the Collège national des gynécologues-obstétriciens français (French College of Gynecologists and Obstetricians) reviewed the carcinological safety of LM and the clinical and radiological follow-up of patients after breast cancer surgery, based on French and international recommendations and a review of the literature. The bibliographic search was conducted via Medline from 2015 to 2022, selecting articles in French and English and applying PRISMA guidelines. RESULTS: A total of 14 studies on the oncological safety of LM, 5 studies on follow-up and 7 guidelines were retained. The 14 studies (6 retrospective, 2 prospective and 6 meta-analyses) had heterogeneous inclusion criteria and variable follow-up, ranging from 38 to 120 months. Most have shown no increased risk of locoregional or distant recurrence after LM. A retrospective case-control study (464 LMs and 3100 controls) showed, in patients who had no recurrence at 80 months, a subsequent reduction in recurrence-free survival after LM in cases of luminal A cancer, highlighting the number of lost to follow-up (more than 2/3 of luminal A cancers). About follow-up after LM, the 5 series showed the high frequency after LM of clinical mass and radiological images (in » of cases), most often corresponding to cytosteatonecrosis. Most of the guidelines highlighted the uncertainties concerning oncological safety of LM, due to the lack of prospective data and long-term follow-up. DISCUSSION AND PERSPECTIVES: The members of the Senology Commission agree with the conclusions of the HAS working group, in particular by advising against LM "without cautionary periods", excessively, or in cases of high risk of relapse, and recommend clear, detailed information to patients before undergoing LM, and the need for postoperative follow-up. The creation of a national registry could address most questions regarding both the oncological safety of this procedure and the modalities of patient follow-up.

OBJECTIVE: Based on an updated review of the international literature covering the different surgical techniques and complications of risk reducing mastectomies (RRM) in non-genetic context, the Commission of Senology (CS) of the College National des Gynécologues Obstétriciens Français (CNGOF) aimed to establish recommendations on the techniques to be chosen and their implementation. DESIGN: The CNGOF CS, composed of 24 experts, developed these recommendations. A policy of declaration and monitoring of links of interest was applied throughout the process of making the recommendations. Similarly, the development of these recommendations did not benefit from any funding from a company marketing a health product. The CS adhered to and followed the AGREE II (Advancing guideline development, reporting and evaluation in healthcare) criteria and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) method to assess the quality of the evidence on which the recommendations were based. The potential drawbacks of making recommendations in the presence of poor quality or insufficient evidence were highlighted. METHODS: The CS considered 6 questions in 4 thematic areas, focusing on oncologic safety, risk of complications, aesthetic satisfaction and psychological impact, and preoperative modalities. RESULTS: The application of the GRADE method resulted in 7 recommendations, 6 with a high level of evidence (GRADE 1±) and 1 with a low level of evidence (GRADE 2±). CONCLUSION: There was significant agreement among the CS members on recommendations for preferred surgical techniques and practical implementation.

OBJECTIVE: The objective was to evaluate the diagnostic value of clinical examination and complementary imaging in the exploration of a breast lump or microcalcifications occurring in a postmenopausal woman taking hormonal replacement therapy (HRT), based on a systematic review of the literature in order to make recommendations for HRT management. METHODS: A literature review was conducted using Medline, Cochrane Library data and international recommendations in French and English until 2020. RESULTS: In the presence of a clinical breast mass in postmenopausal women, there is no clinical evidence to rule out cancer. A double evaluation by mammography and ultrasound is recommended and allows the imaging to be classified into 5 BI-RADS categories. The diagnostic management of masses classified BI-RADS 4 and 5 should be based on percutaneous sampling, with microbiopsy being the first step. A total of four situations may arise: 1. Clinical examination has detected a breast mass, but there is no imaging abnormality. In this case, the imaging NPV is high (>96%). If the clinical lesion increases in size, a tissue biopsy should be performed, while continued routine breast screening is recommended if the lesion remains stable and HRT can be continued. 2. Clinical examination, mammography, and ultrasound are in favour of a cyst. Simple cysts can be punctured if painful. There is no contraindication to continuing HRT in the case of simple cysts. Management options for complicated and complex cysts are no different from those offered to women without HRT. Continuation of HRT must consider their histological nature. 3. Clinical examination, mammography, and ultrasonography suggest a benign solid tumour. The management of these benign breast lesions (fibroadenoma ) is not different in women taking an HRT and there is no contraindication to continue the HRT. 4: Clinical examination, imaging and microbiopsy diagnose a malignant tumour. It is imperative that the HRT be stopped, whatever the hormonal dependence of the tumour and whether it is invasive or in situ. The management of the cancerous tumour must consider the updated breast cancer treatment guidelines. In the presence of microcalcifications, the course of action to be taken depends on the BI-RADS classification, established according to the morphology and arrangement of the calcifications. In case of suspicious microcalcifications (BI-RADS 4 or 5), a guided macrobiopsy should be performed. Diagnostic and therapeutic management in these patients is no different from that offered to women without HRT. Discontinuation of HRT is necessary in cases of malignancy (in situ or invasive cancer). CONCLUSION: A rigorous multidisciplinary approach is necessary for the exploration of a breast mass or microcalcifications in a postmenopausal woman.

BACKGROUND: Ventriculoperitoneal shunt is the most common treatment to manage hydrocephalus; it is unfortunately burdened by up to 25% of complications. The peritoneal approach may expose patients to many complications, however the formation of a liver pseudocyst is a rare occurrence, and its mechanisms are still largely unknown. CASE REPORT: We report the case of a 69-year-old woman with ventriculoperitoneal shunt, inserted for the management of post aneurysmal subarachnoid hemorrhage hydrocephalus, presenting to the Accident and Emergency for acute cholecystitis. Besides confirming the diagnosis, an ultrasound investigation revealed the presence of a hepatic cyst. Conservative treatment with antibiotics and non-steroidal anti-inflammatory drugs was performed with favorable outcome and resorption of the cyst. Interestingly the patient kept on presenting several similar episodes managed well by non-steroidal anti-inflammatory drugs alone, each of them associated with transient symptoms and signs of ventriculoperitoneal shunt malfunction. Computerized Tomography brain and lumbar puncture were normal, whereas CT abdomen showed the ventriculoperitoneal shunt distal catheter passing through the hepatic cyst. Given the ventriculoperitoneal shunt malfunction, in the context of an infective/inflammatory process a conversion of the ventriculoperitoneal shunt into a ventriculo-atrial shunt was carried out with successful clinical outcome. CONCLUSION: Based on current literature we propose a clinical and radiological classification of such pseudocysts related to ventriculoperitoneal shunt. Clinical presentation, diagnostic findings and management options are proposed for each type: purely infective, spurious (infective/inflammatory) and purely inflammatory. In the absence of system infection, a simple replacement of the distal catheter seems to be the best solution.

PURPOSE: The goal of this data challenge was to create a structured dynamic with the following objectives: (1) teach radiologists the new rules of General Data Protection Regulation (GDPR), while building a large multicentric prospective database of ultrasound, computed tomography (CT) and MRI patient images; (2) build a network including radiologists, researchers, start-ups, large companies, and students from engineering schools, and; (3) provide all French stakeholders working together during 5 data challenges with a secured framework, offering a realistic picture of the benefits and concerns in October 2018. MATERIALS AND METHODS: Relevant clinical questions were chosen by the Société Francaise de Radiologie. The challenge was designed to respect all French ethical and data protection constraints. Multidisciplinary teams with at least one radiologist, one engineering student, and a company and/or research lab were gathered using different networks, and clinical databases were created accordingly. RESULTS: Five challenges were launched: detection of meniscal tears on MRI, segmentation of renal cortex on CT, detection and characterization of liver lesions on ultrasound, detection of breast lesions on MRI, and characterization of thyroid cartilage lesions on CT. A total of 5,170 images within 4 months were provided for the challenge by 46 radiology services. Twenty-six multidisciplinary teams with 181 contestants worked for one month on the challenges. Three challenges, meniscal tears, renal cortex, and liver lesions, resulted in an accuracy>90%. The fourth challenge (breast) reached 82% and the lastone (thyroid) 70%. CONCLUSION: Theses five challenges were able to gather a large community of radiologists, engineers, researchers, and companies in a very short period of time. The accurate results of three of the five modalities suggest that artificial intelligence is a promising tool in these radiology modalities.

The objective of this review was to determine whether there is an association between hyperthyroidism and the risk of developing a breast cancer from the analysis of data in the literature. METHOD: The analyzed articles were extracted from the PUBMED database from 2002 to 2017 using the following keywords "hyperthyroidism AND breast cancer" and "thyroid AND breast cancer". RESULTS: A total of 22 studies were selected, including 8 cohort studies, 12 case-control studies and 2 meta-analyzes. Of these 22 studies, 15 have established a significant epidemiological or biological link between hyperthyroidism and breast cancer. Five of them were particularly interested in Graves' disease, and four demonstrated a positive association between this disease and the onset of breast cancer, especially within three years from the thyropathy diagnosis. These different studies also highlighted the increased risk of breast cancer seen in overweight or postmenopausal women. Contradictions persist over the types of mammary cancers observed and their prognosis. CONCLUSION: This review reveals that women with hyperthyroidism appear to have a moderately high risk of breast cancer (RR<2). These data are corroborated by solid physiopathological hypotheses. Regardless of the type of thyropathy responsible for hyperthyroidism, care should be taken to ensure that these patients receive a clinical examination of the breasts on an annual basis and mammographic screening every 2 years from the age of 50 years.

Triple negative breast cancers have the highest relapse risk and the least favourable prognosis of all breast cancer subtypes, leading to an escalation of chemotherapy, substantially during recent years. Secretory carcinoma of the breast is a rare triple negative neoplasm, first described in children but more often presenting in adults. We report a case of a 70-years-old woman, initially diagnosed on the biopsy with a triple negative infiltrating Not Otherwise Specified (NOS) carcinoma of the breast, before it was later correctly identified as a secretory carcinoma, notably because of an abundant intra and extracellular secretory material. This new diagnosis, confirmed by fluorescence in-situ hybridization analysis showing ETS variant 6 (ETV6) gene rearrangement, allowed the de-escalation of chemotherapy therapy. Four years later, the patient is free of recurrences.

Pelvic ring fractures when caused by trauma, either violent or in demineralized bone, generally consist of injuries in both the anterior (pubic symphysis and rami) and posterior (iliac wing, sacrum, sacroiliac joint) portions. Injury classifications are based on injury mechanism and pelvic stability, and are used to determine treatment. Acetabular fractures, associated or not to pelvic ring disruption, are classified on the basis of fracture line, into elementary fractures of the acetabular walls, columns and roof, and into complex fractures. Fractures of the proximal end of the femur occur often on demineralized bone following low-energy trauma. The fractures are categorized by anatomic location (neck, trochanter and subtrochanteric region) and degree of displacement. These variables determine the risk of osteonecrosis of the femoral head, which is the main complication of such fractures.

This article reviews and explains the basic physical principles of metal-induced MRI artifacts, describes simple ways to reduce them, and presents specific reduction solutions. Artifacts include signal loss, pile-up artifacts, geometric distortion, and failure of fat suppression. Their nature and origins are reviewed and explained though schematic representations that ease the understanding. Then, optimization of simple acquisition parameters is detailed. Lastly, dedicated sequences and options specifically developed to reduce metal artifacts (VAT, SEMAC, and MAVRIC) are explained.

OBJECTIVES: Main objective was to compare accuracy of ultrasonography and MRI for antenatal diagnosis of placenta accreta. Secondary objectives were to specify the most common sonographic and RMI signs associated with diagnosis of placenta accreta. MATERIAL AND METHODS: This retrospective study used data collected from all potential cases of placenta accreta (patients with an anterior placenta praevia with history of scarred uterus) admitted from 01/2010 to 12/2014 in a level III maternity unit in Strasbourg, France. High-risk patients beneficiated antenatally from ultrasonography and MRI. Sonographic signs registered were: abnormal placental lacunae, increased vascularity on color Doppler, absence of the retroplacental clear space, interrupted bladder line. MRI signs registered were: abnormal uterine bulging, intraplacental bands of low signal intensity on T2-weighted images, increased vascularity, heterogeneous signal of the placenta on T2-weighed, interrupted bladder line, protrusion of the placenta into the cervix. Diagnosis of placenta accreta was confirmed histologically after hysterectomy or clinically in case of successful conservative treatment. RESULTS: Twenty-two potential cases of placenta accreta were referred to our center and underwent both ultrasonography and MRI. All cases of placenta accreta had a placenta praevia associated with history of scarred uterus. Sensibility and specificity for ultrasonography were, respectively, 0.92 and 0.67, for MRI 0.84 and 0.78 without significant difference (p>0.05). The most relevant signs associated with diagnosis of placenta accreta in ultrasonography were increased vascularity on color Doppler (sensibility 0.85/specificity 0.78), abnormal placental lacunae (sensibility 0.92/specificity 0.55) and loss of retroplacental clear space (sensibility 0.76/specificity 1.0). The most relevant signs in MRI were: abnormal uterine bulging (sensitivity 0.92/specificity 0.89), dark intraplacental bands on T2-weighted images (sensitivity 0.83/specificity 0.80) or placental heterogeneity (sensitivity 0.92/specificity 0.89). Association of two sonographic or MRI signs had the best sensitivity/specificity ratio. DISCUSSION AND CONCLUSION: Ultrasonography and RMI represent two interesting and complementary diagnostic tools for antenatal diagnosis of placenta accreta. Because of its cost and accessibility, ultrasonography remains the first in line to be used for diagnosis. Use of an analytical grid for diagnosis of placenta accreta could be helpful.

Olfactory bulb (OB) volume evaluation by magnetic resonance imaging (MRI) has been demonstrated to be related to olfactory dysfunction in many different diseases. Olfactory dysfunction is often overlooked in Bardet-Biedl syndrome (BBS) patients and is rarely objectively evaluated by MRI. We present a series of 20 BBS patients with olfactory dysfunction. The OB was evaluated separately and blindly by two radiologists (SR and SM) with 3 Tesla MRI imaging comparatively to 12 normal control subjects by global visual evaluation and by quantitative measurement of OB volume. In the 12 control cases OB visual evaluation was considered as normal in all cases for radiologist (SR) and in 10 cases for radiologist (SM). In the 20 BBS patients, OB visual evaluation was considered as abnormal in 18 cases for SR and in all cases for SM. OB volumetric evaluation for SR and SM in BBS patients was able to provide significant correlation between BBS and olfactory dysfunction. This study indicates that OB volume evaluation by MRI imaging like structural MRI scan for gray matter modifications demonstrates that olfactory dysfunction in BBS patients is a constant and cardinal symptom integrated in a genetical syndrome with peripheral and central olfactory structure alterations.
