Magnetic Resonance Imaging-Guided Focused Ultrasound Surgery for the Treatment of Symptomatic Uterine Fibroids
2017
Uterine fibroids, the most common benign tumor in women of childbearing age, may cause symptoms including pelvic pain, menorrhagia, dysmenorrhea, pressure, urinary symptoms, and infertility. Various approaches are available to treat symptomatic uterine fibroids. Magnetic Resonance-guided Focused Ultrasound Surgery (MRgFUS) represents a recently introduced noninvasive safe and effective technique that can be performed without general anesthesia, in an outpatient setting. We review the principles of MRgFUS, describing patient selection criteria for the treatments performed at our center and we present a series of five selected patients with symptomatic uterine fibroids treated with this not y…
Malignancy course of pituitary adenoma in MEN1 syndrome: Clinical-Neuroradiological signs
2020
Pituitary carcinomas (PCa) are extremely rare, indistinguishable from pituitary adenomas on histopathological grounds and have a poor prognosis. Most PCa start as PRL or ACTH secreting tumors in males, with relapsing invasive behaviour, refractoriness to medical and radiotherapy and increasing hormonal levels. The presence of distant metastases is still required for the diagnosis of PCa. The association with genetic endocrine diseases must be taken into account, since it adds further risk of evolution towards malignancy. Intradural spinal metastases have also been reported, so a complete craniospinal MR evaluation is recommended, when clinically indicated. We report a case of PCa, associate…
CEUS LI-RADS: a pictorial review
2020
AbstractContrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic tool in the imaging work-up of cirrhotic patients at risk for developing hepatocellular carcinoma (HCC). In particular, CEUS Liver Imaging Reporting and Data System (LI-RADS) provides standardized terminology, interpretation, and reporting for the diagnosis of HCC. The aim of this pictorial essay is to illustrate CEUS features of nodules discovered at US in cirrhotic liver according to LI-RADS categorization.

LIPOCORISTOMA DELL’ANGOLO PONTO-CEREBELLARE: UN NUOVO NOME PER UNA VECCHIA CONOSCENZA
2019
SCOPO DEL LAVORO: I lipochoristomi sono rari tumori benigni (0.1% di tutti i processi espansivi dell’angolo ponto-cerebellare) che in passato si riteneva derivassero dalle cellule della primitiva meninge e pertanto venivano definiti come lipomi dell’angolo ponto-cerebellare (o del condotto uditivo interno). Oggigiorno sono più propriamente definiti come "coristomi lipomatosi" (o lipocoristomi) poiché si è dimostrato che originano dal tessuto mesenchimale proprio del nervo vestibolo-cocleare. Scopo del presente lavoro è quello di presentare dei casi di lipocoristoma alla luce dei dati oggi riportati nella più recente letteratura. MATERIALI E METODI: Saranno presentati casi di pazienti con ri…

TRANS-FUSIMO: Preliminary in-vivo animal results of MR-guided Focused Ultrasound of liver under respiratory motion
2018
Background: Treating liver tumors using FUS poses a great challenge due to the respiratory motion of the target and by the rib cage obscuring the anatomical location of the malignancy. In the EU FP7 project TRANS-FUSIMO (www.trans-fusimo.eu) a novel treatment software has been developed to support MR guided focused ultrasound treatment of liver lesions through electronic real-time beam steering of the ultrasound transducer. Prior to clinical use we conduct an in-vivo animal trial using the TRANS-FUSIMO treatment system (TTS) to evaluate the safety and the technical efficacy and efficiency of generation predefined necrotic lesions in the healthy liver. Material and Methods: The pre-clinical …
