Abstract
The treatment for breast cancer is sometimes long and requires a multidisciplinary approach. In 2010, in our centre, we began to perform fat grafting for breast reconstruction using the so-called 'reverse expansion' technique. This consists of the insertion of a skin expander during mastectomy, in its expansion and then in its gradual deflation in the surgical theatre during fat grafting. We performed a complete breast reconstruction in 57 patients by reverse expansion. We harvested fat from the fat excess areas using a normal liposuction cannula. From each patient, an average of 640 ccs of was collected and then centrifuged in a 4000-rpm centrifuge for 3 min. The obtained adipocytes were then injected in the operated breast using a normal lipofilling cannula. We injected an average of 318.05 ccs of adipocytes for each patient each time. The average number of sessions per patient was 3.6. Reverse expansion can be a safe and effective technique for breast reconstruction in all the breast cancer patients.

Abstract
BACKGROUND In gradient echo magnetic resonance imaging (MRI), intravascular thrombi (IT) can appear as vascular susceptibility artifacts, linked to local presence of intra-arterial deoxyhaemoglobin, and called susceptibility vessel signs (SVS). AIMS Our objectives were to evaluate the sensitivity of susceptibility-weighted sequences, such as T2* weighted angiography (SWAN) in the visualization of SVS compared with T2*, to consider whether it enabled a better understanding of the importance of SVS, and to compare cerebral circulation regulation profiles according to the localization of the SVS (i.e. proximal or distal). METHODS We prospectively studied the clinical and imaging data of 78 consecutive patients admitted for acute cerebral ischemia to the stroke unit of Besançon University Hospital between 1 April 2009 and 31 January 2010. RESULTS An SVS was visualized in 44/78 (56%) patients using SWAN and in 13/78 (16%) patients using T2*. All the SVS visible using T2* were also visible on the SWAN. The inter-observer kappa score was 0·72 [CI (0·53-0·91)] for T2*, 0·72 [CI (0·57-0·87)] for SWAN, and weighted kappa was 0·77 [CI (0·61-0·92)] for both T2* and SWAN. When an MCA occlusion was visible on MRA imaging (22/78 patients), a SVS was visualized in 7/22 cases (31·8%) using T2* and in 20/22 cases (91%) using SWAN. When the occlusion was visible in the M1 or M2 segments (17/78 patients), an SVS was visualized in 6/17 cases (35·3%) using T2* and in 15/17 cases (88·2%) using SWAN. When the occlusion was visible in the M3 segment (5/78 patients), an SVS was visualized in 1/5 cases (20%) using T2* and in 5/5 cases (100%) using SWAN. Presence of SVS was not associated with cardioembolic etiology of the stroke. CONCLUSIONS SWAN was more sensitive than T2* in the visualization of SVS in the intracranial arteries during the acute phase of ischemic stroke. Our study shows that the low number of SVS visualized using T2* in previous studies is probably related to a lack of sensitivity of the sequence, rather than to the nature or age of the thrombus. The greater sensitivity of SWAN seems to be linked to the visualization of SVS in cases of small thrombi.

Abstract
AIM Lipofilling is a part of the clinical practice for breast reshaping in patients who underwent surgery for breast cancer. A strong debate in the Literature is open about a higher risk of cancer relapse caused by growth factors produced by adipocyte stem cells after their engraftment in the recipient tissue. Nowadays there is no agreement over the use of autologous fat tissue for the correction of aesthetic defects following breast conservative surgery. METHODS We have considered 151 patients who underwent a breast conservative surgery in the period April 2004-April 2009, followed by one or more lipofilling sessions in the period June 2006-August 2012. A careful pre-operative evaluation of the tumor characteristics has been made, through imaging exams, MRI included. An intraoperative evaluation of the tumor dimensions and its distance from the surgical edges has also been made, followed by a microscopic analysis through a shaving technique. Lipofilling has been offered to all the patients on average 24 months after surgery. RESULTS We have found no cancer relapses after a mean follow up of 45 months (17-76) after lipofilling and of 69 (27-100) months after surgery. CONCLUSIONS Considering oncologic surgery, we can affirm that lipofilling is safe for the risk of cancer relapses, if performed using all the parameters included in our clinical protocol.

Abstract
AIM There is an increased expectation from breast cancer patients to retain their "normal breast appearance". To help to achieve this expectation, many radiologic exams have been created to get the exact extension and position of the tumor. MRI is effective to obtain correct information about neoplasms, especially those with shaded edges, like DCIS. MRI might change the surgical project, thus avoiding second operations for cancer relapses. METHODS We have performed MRI to all the patients except those with big lesions or adypous breasts. We have chosen for reconstruction various oncoplastic techniques. We have had early complications in 98/489 (20%) cases. RESULTS As late complications, we have found scar retractions and minus areas in 20/489 cases (4.08%), while we have found asymmetries and bigger deformities in 34/489 cases (6.95%). We have not found any cancer relapse after one year, we have had 3 cases of relapse (0.6%) after five years of follow-up, after 5, 4 and 2 years. Our good oncologic and plastic results have to be attributed to many factors, among which stands out the MRI done in all the cases. CONCLUSION We think that an immediate breast reshaping following quadrantectomy is the best esthetic and psychologic option for breast cancer patients.

Abstract
In the last years there has been a growing demand of plastic surgery for soft tissue reconstruction. In response to this, many biological and synthetic devices have been produced, aiming to allow wide and complex body reshapings. Acellular dermal matrices are one of these devices, and are made of human or animal tissues made acellular after their sampling. They are used for cervical, breast and abdominal wall reconstruction. Tutopatch®, generally used for face reconstruction or neurosurgery, is made of acellular bovine pericardium, and its high amount of collagen allows a fast tissue healing and a scaffold for the surrounding tissue regeneration. In our case report Tutopatch® has been used in immediate breast reconstruction after mastectomy. This device has been used to close laterally the subpectoral pocket, allowing a bigger volume prosthesis to be placed We have not experienced particular postoperatory complications, and after 12 months of follow up we have found a valid functional and aesthetic result. We consider Tutopatch® as a valid alternative to other acellular dermal matrices specifically designed for breast reconstruction.

Abstract
Patients with GERD and atypical symptoms represent a particular category with a less clear definition of the physiopatological mechanisms and thereby need a precise attention toward the indication to surgery. The less good response to surgery therefore requires a careful evaluation and selection of patients with atypical symptoms.

Abstract
The purpose of this study was to demonstrate the improvement in diagnostic quality and diagnostic accuracy of SonoVue microbubble contrast-enhanced ultrasound (CE-US) versus unenhanced ultrasound imaging during the investigation of extracranial carotid or peripheral arteries. 82 patients with suspected extracranial carotid or peripheral arterial disease received four SonoVue doses (0.3 ml, 0.6 ml, 1.2 ml and 2.4 ml) with Doppler ultrasound performed before and following each dose. Diagnostic quality of the CE-US examinations was evaluated off-site for duration of clinically useful contrast enhancement, artefact effects and percentage of examinations converted from non-diagnostic to diagnostic. Accuracy, sensitivity and specificity were assessed as agreement of CE-US diagnosis evaluated by an independent panel of experts with reference standard modality. The median duration of clinically useful signal enhancement significantly increased with increasing SonoVue doses (p< or =0.002). At the dose of 2.4 ml of SonoVue, diagnostic quality evaluated as number of inconclusive examinations significantly improved, falling from 40.7% at baseline down to 5.1%. Furthermore, SonoVue significantly (p<0.01) increased the accuracy, sensitivity and specificity of assessment of disease compared with baseline ultrasound. SonoVue increases the diagnostic quality of Doppler images and improves the accuracy of both spectral and colour Doppler examinations of extracranial carotid or peripheral arterial disease.

MRI is the sole radiological examination to be obtained if abnormal menses, galactorrhea or anovulation evokes the diagnosis of prolactinoma. Nevertheless, iatrogenic hyperprolactinemia or presence of big prolactin has to be ruled out before MRI is asked for. MRI of the pituitary gland must be technically optimal; analysis of the images has to be directed by clinical and biological data.

Abstract
The indications for treating carotid artery stenosis are related to the symptomatic nature of the lesion and the degree of stenosis. Duplex sonography is adequate for screening. While some groups believe that Duplex US alone or in combination with transcranial Doppler imaging may be sufficient for presurgical evaluation, it often is recommended to complete the evaluation with either MRA or CTA. Both techniques are advantageous since they allow evaluation of the cervical and intracranial arteries as well as cerebral parenchyma hence providing valuable information prior to definitive management. Catheter angiography remains indicated in patients with multi-vessel disease and ischemic cardiomyopathy, when results at non-invasive evaluation are discordant or in an emergency setting. Duplex US is used for routine follow-up of non-surgical lesions and after endarterectomy. Transcranial Doppler as well as advances in MRA and CTA techniques will be reviewed. Even though the treatment of atherosclerotic carotid artery stenoses remains primarily surgical, specific considerations related to angioplasty will be reviewed. Finally, diseases of the intracranial carotid artery and non-atherosclerotic diseases (dissection...) will also be discussed.

Abstract
Rathke's cleft cyst (RCC) are frequent benign cystic sellar lesions. Most RCC are small, intrasellar and asymptomatic. Larger cysts may compress adjacent structures and rarely become symptomatic. Diagnosis is strongly suggested at MRI by the presence of a midline non-enhancing lesion located exactly between the anterior and posterior lobes of the pituitary gland. Even if its signal is variable and related to intracystic protein concentration, it must be homogeneous with no fluid-fluid level. Once a diagnosis of RCC made, routine MR and clinical follow-up is sufficient for incidental asymptomatic cysts whereas the rare symptomatic lesions are neurosurgically resected.

Abstract
The authors report their 10 year experience on postsurgical MRI of the sphenoidal region. All patients underwent MRI examination 4 days after surgery, then between 2 and 3 months and one year or more after surgery. The reproducibility of pulse sequences is mandatory to make a diagnosis of recurrent adenoma as early as possible.

Abstract
There are two species of the genus Echinococcus, Echinococcus multilocularis (also called alveolar hydatid) and Echinococcus granulosus, characterized by distinct growth features in humans. The main endemic regions for human alveolar echinococcosis (AE) caused by E. multilocularis are Central Europe, Russia, Turkey, Japan, China, eastern France and North America. Human echinococcosis is usually caused by an intrahepatic growth of parasitic larvae. Cerebral occurrence of E. multilocularis disease is rare, accounting for only 1% of cases, and is generally considered to be fatal. This report presents two cases of intracerebral E. multilocularis disease which occurred in two infected patients with AE pulmonary metastases. The anatomical and clinical features are discussed. Our retrospective survey would indicate that surgical treatment should be envisaged whenever possible.

Abstract
OBJECTIVE To report the experience of using various Gadolinium chelates as contrast media in digital subtraction angiography in patients with relative or absolute contraindications for iodinated contrast agents. MATERIAL and Methods. Forty-two arteriograms were performed in 39 consecutive patients using Gadolinium chelates (gadoteridol, gadodiamide, and gadopentetate dimeglumine). The vasculature of the brain, of the upper and lower limbs and the renal arteries were examined. Among these 39 patients, 17 were treated by various endovascular procedures. RESULTS In 40 examinations out of 42, the angiographic result was satisfactory, allowing either a diagnostic evaluation or an endovascular therapeutic procedure. Clinical tolerance was excellent. In one case of renal failure that was reported after angiography, the patient had received both iodine and gadolinum-based contrast agents. CONCLUSION Gadolinium appears to be an interesting alternative for arteriography in patients with absolute or relative contraindication to iodinated contrast agents, and also seems to demonstrate efficacy during endovascular therapeutic procedures.

Abstract
We report the case of a 60-year old woman presenting, 3 days after arterial embolization of a dural arteriovenous fistula, with diplopia and gait disturbance in relation with right oculomotor nerve palsy and cerebellar dysfunction. On T2 weighted MR images, several hyperintense areas appeared in the pons and the midbrain. After one month, clinical symptoms and diffuse hyperintense areas resolved spontaneously, as the patient was treated by anti-vitamin K. This complication probably corresponds to reversible pontine venous congestion caused by poor venous drainage of the dural arteriovenous fistula.

Abstract
The diagnosis of acoustic neuroma is usually evoked in a patient presenting with a long history of hearing disturbance in whom an enhancing lesion within the internal auditory canal and/or the cerebellopontine angle is found on MRI. Hypervascularity with arteriovenous shunting and early filling of enlarged veins is a common feature of malignancy and has been reported very rarely in benign acoustic neuroma. We present the case of a patient without hearing disturbance, who showed a highly vascular lesion with no component in the internal auditory canal, making the preoperative diagnosis of acoustic neuroma very challenging. We discuss here the intracisternal site of origin and hypervascularity of acoustic neuroma, and also the differential diagnoses and management of such tumors.

Abstract
Specific MR techniques are required for optimal detection of adenocorticotropic hormone secreting adenomas responsible for Cushing's disease. Adequate MR sequences, high resolution coronal T1 and T2 - weighted images, dynamic MR imaging, post-gadolinium delayed images, dose of gadolinium adjusted for each sequence can routinely demonstrate pituitary adenomas less than 3 mm in Cushing's disease.

Abstract
PURPOSE To illustrate that residual normal pituitary gland may show hyperintense signal on T1-weighted image after medical treatment of pituitary prolactinoma. MATERIAL and methods. Three patients treated with bromocriptine for a prolactinoma and showing hyperintense signal of the residual normal pituitary tissue on T1-weighted images were studied. In all patients, measurements of the anterior pituitary gland signal (APGS) and the temporal lobe white matter signal (TLWMS) were obtained by a "region of interest" (ROI) on coronal T1-weighted images. The APGS/TLWMS ratios were calculated and compared to those of a control group of 30 normal subjects. RESULTS In the three patients, the measurements obtained by ROI confirmed the visual impression of high signal of the residual normal pituitary tissue. Ratios were ranging from 1.15 to 1.21, while they were ranging, in the control group from 0.92 to 1.09. CONCLUSION In patients with prolactin-secreting adenoma seen after medical treatment, high signal of the residual normal pituitary tissue can be observed, probably due to cellular hyperactivity as it can be noticed during some physiological states. This pattern has to be differentiated from other pituitary abnormalities demonstrating T1 hyperintensity such as hemorrhagic changes of a prolactinoma.

Abstract
We describe the normal dural enhancement patterns of the sellar region and determine whether the duramater is affected by pituitary macroadenomas. Dural enhancement appeared to be usually abnormal in 20 patients with pituitary macroadenoma compared with 20 control patients, mainly at the planum sphenoidale and carotid sulcus. However dural changes are subtle and their recognition requires knowledge of the normal enhancement patterns. Dural changes, reported in a variety of inflammatory and infectious dural diseases and after surgery, are not specific and may be also seen in pituitary macroadenomas.

Abstract
Ultrasound contrast agents are introducing a new vision to ultrasonography. The increase in the Doppler signal intensity improves difficult examinations. Technical failures in the study of transcranial, liver and renal vessel might be rescued with the injection of these new compounds. The introduction of specific image sequences such as harmonic imaging and pulse inversion imaging allows detection of parenchymal enhancement in liver and renal examinations. The injection of ultrasound contrast agents also provides dynamic quantitative information to develop functional imaging. However, it is mandatory to understand the interaction with the ultrasound beam in order to optimise their use and define the adequate ultrasound sequence.

Abstract
Computed tomography (CT) is widely used for early evaluation of acute strokes. Most importantly, CT excludes acute hemorrhage or other diseases mimicking ischemia. Therefore, CT is the main imaging examination in patients with brain ischemia and when antithrombotic agents are being considered. During the first hours after acute ischemic stroke, the CT does not usually show much in the first 24 hours. However, early abnormal findings on CT scan have been described such as the hyperdense middle cerebral artery sign (HMCAS), and reduced contrast attenuation of the cerebral parenchyma. HMCAS reflects arterial occlusion. Early parenchymal abnormalities, the attenuation of lentiform nucleus (ALN), loss of the insular ribbon (LIR) or hemispheric sulcus effacement (HSE) occur less frequently and they are positive criteria for cerebral in progress. Early parenchymal abnormalities might also predict subsequent infarct extension and hemorrhagic transformation. Therapeutic trials of ischemia in MCA territory involved decision making when the CT may not show obvious ischemic changes. Finally, initial CT findings may also help to predict response to therapy.

Abstract
Increase in transcranial Doppler ultrasound flow velocities in the major basal arteries correlates with symptomatic vasospasm. Transcranial Doppler examinations are performed using a pulsed Doppler Probe via the trans temporal approach. Transcranial colour-coded real time sonography can be useful and help to identify the cerebral arteries. Maximum flow velocities of > 200 cm/sec are associated with cerebral ischemia and infarction. A maximum rise in Doppler velocity of more than 50 cm/sec/24 h is correlated with poor outcome. Using a diagnostic cutoff of 130 cm/sec a 87% positive predictive value can be obtained using TCD in the middle cerebral artery. Numerous factors affect Doppler flow velocities and may lead to erroneous conclusions about the presence or absence of vasospasm. Flow velocity is directly related to cerebral blood flow. Intracranial pressure, blood pressure and volume, hematocrite and subarachnoid hemorrhage affect Doppler flow velocities. False-negative examinations of vasospasm using TCD are associated with distal vasospasm, severe spasm of the carotid siphon, chronic high blood pressure and increased intracranial pressure.
