STORIA NATURALE DI OSTEONECROSI DA BIFOSFONATI PER OS. A CASE REPORT

Aspetti radiologici nell'osteonecrosi dei mascellari da bifosfonati e proposta di una classificazione radiologica in funzione dell'evoluzione clinica.

Videofluorography and MDCT findings in a case of pharyngeal perforation after anterior cervical spinal surgery with fusion (ACSF)

Purpose Anterior cervical spinal surgery with fusion (ACSF) is the most widely used technique in the management of cervical spondylosis or disc herniation. A case of pharyngeal perforation after ACSF demonstrated by videofluorography and MDCT is described. Methods A 39-year-old man, recently undergone to ACSF for interbody C3-C5 fusion with anterior cervical plate and screws, was submitted to a pharingoesophageal videofluorography and 64 row-MDCT of the neck before and after oral administration of iodine contrast medium for persistent high dysphagia. Results In the plain radiograph a fractured screw was detected, anterolaterally displaced on the right to the cervical spine, outside the phar…

MRgFUS Uterine Fibroids treatments in Sicily: Preliminary Results and comparison of a Semi-Automatic and manual contouring

Background: Traditional surgery for uterine fibroids treatments (e.g. myomectomy, hysterectomy) offers very invasive therapeutic approaches, which not always preserve reproductive potential of the woman. MRgFUS (MR guided Focused UltraSound) is a new and non-invasive technique for uterine fibroids treatment, not requiring hospitalization and recovery time [1]. On June 2011 and July 2012 the first treatments were started at HSR-Giglio Hospital in Cefalù and at University Hospital (DIBIMEF) in Palermo. An initial assessment of MRgFUS treatment was made by computing the thermally-ablated volume of uterine fibroid. This volume was evaluated considering the NPV (Non Perfused Volume) on a post-t…

IMAGING FINDINGS SYSTEMATIZATION AND IMAGING STAGING PROPOSAL IN BISPHOSPHONATES ASSOCIATED OSTEOMYLITIS/OSTEONECROSIS OF THE JAWS

INTRODUZIONE I Bifosfonati (BPs), farmaci analoghi al pirofosfato, sono usati nel trattamento dell’osteoporosi, nella malattia di Paget, nel mieloma multiplo e nelle metastasi ossee. Sebbene siano molto utili nella sintomatologia osteolitica, dal 2003 è stata descritta la correlazione tra la loro somministrazione e l’insorgenza dell’osteonecrosi dei mascellari (BRONJ). Il nostro studio si propone di descrivere la superiorità delle immagini TC nei pazienti in cura con BPs affetti da BRONJ, e di raggruppare gli stessi in accordo con una classificazione radiologica basata sulla presenza o meno dei segni dell’osteomielite/osteonecrosi e delle successive complicanze. Si dimostra, inoltre, l’impo…

La pelvi operata: nuova anatomia e complicanza

ANATOMICAL VARIATIONS OF THE SPHENOID SINUS ASSESSED WITH MDCT

Background The aim of this study was to assess the incidence of the anatomical variations of the sphenoid sinus in 293 patients studied by multidetector computed tomography (MDCT). Materials and Methods The MDCT (64 rows) studies of the paranasal sinuses of 293 patients, performed in 2006-2009, were reviewed to assess anatomical variations of the sphenoid sinus and related neurovascular structures. Anatomical variations were evaluated on 1 mm thick MPR reformations, displayed on a high resolution workstation screen. Pneumatization of the anterior clinoid process (ACP), pterygoid recess (PR), protrusion of the internal carotid artery (ICA), optic nerve (ON), maxillary and vidian nerve into t…
