Objective: To evaluate the radiological behavior of individual NICE lesions over time.

Methods: Patients included in a retrospective national multicentric inception cohort were analyzed.

Facet joint syndrome: from diagnosis to interventional management.

Low back pain (LBP) is the most common pain syndrome, and is an enormous burden and cost generator for society. Lumbar facet joints (FJ) constitute a common source of pain, accounting for 15-45% of LBP. Facet joint degenerative osteoarthritis is the most frequent form of facet joint pain.

Greater occipital nerve MR tractography: Feasibility and anatomical considerations.

Background And Purpose: To assess the feasibility of greater occipital nerve (GON) tractography using a fully automated tractography technique on the whole-neck volume, in comparison with anatomical knowledge.

Methods: Healthy subjects were consecutively included in this study if they had no history or symptoms of headache or brain disorder. A 3T MRI scanner with a 32 channel head coil was used.

The relationship between post-traumatic ossicular injuries and conductive hearing loss: A 3D-CT study.

Purpose: After a trauma, the conductive ossicular chain may be disrupted by ossicular luxation or fracture. Recent developments in 3D-CT allow a better understanding of ossicular injuries. In this retrospective study, we compared patients with post-traumatic conductive hearing loss (CHL) with those referred without CHL to evaluate the relationship between ossicular injuries and CHL.

Patient eligibility for thrombectomy after acute stroke: Northern French Alps database analysis.

Background: Since 2015, the emergence of mechanical thrombectomy as standard care in acute stroke has involved organizational changes not only for stroke centers, but also for entire emergency regional networks. The aim of our study was to assess the proportion of ischemic stroke patients, admitted to stroke units in the Northern French Alps within the first 6h of onset, eligible for thrombectomy.

Methods: This study retrospectively analyzed the clinical and radiological data of all acute stroke patients hospitalized at three stroke units of the Northern French Alps Emergency Network (RENAU) in 2014.

Reduced CMRO₂ and cerebrovascular reserve in patients with severe intracranial arterial stenosis: a combined multiparametric qBOLD oxygenation and BOLD fMRI study.

Multiparametric quantitative blood oxygenation level dependent (mqBOLD) magnetic resonance Imaging (MRI) approach allows mapping tissular oxygen saturation (StO2 ) and cerebral metabolic rate of oxygen (CMRO2 ). To identify hemodynamic alteration related to severe intracranial arterial stenosis (SIAS), functional MRI of cerebrovascular reserve (CVR BOLD fMRI) to hypercapnia has been proposed. Diffusion imaging suggests chronic low grade ischemia in patients with impaired CVR.

An acute ischemic stroke secondary to sphenoid sinusitis.

Acute isolated sphenoid sinusitis is a relatively uncommon entity. Because its symptoms and clinical findings are nonspecific, it can be easily misdiagnosed. Left unrecognized and untreated, it can lead to several well-known and severe complications, including meningitis, cerebral abscess, cavernous sinus thrombosis, and epidural or subdural empyema.

Giant osteoma of the maxillary sinus--diagnosis and management.

Osteomas are rare, slow-growing, benign bone tumors that preferentially develop in the paranasal sinuses. We report a case of a giant osteoma of the left maxillary sinus in a 29-year-old man which was diagnosed by imaging and endoscopy and treated surgically because of the patient's symptoms and maxillary sinus distortion. Given the large volume and location of the osteoma, resection was performed through an external sublabial approach, according to the Rouge-Denker technique.

How helical CT helps the surgeon in oculo-orbital trauma.

Whether isolated or associated with craniofacial lesions, traumatic oculo-orbital injuries occur frequently. Radiological evaluation is often necessary to appropriately manage the trauma-related vision loss and oculomotor disturbance. In the emergency setting and after clinical examination, helical CT scanning is the optimal imaging technique for displaying injuries of the orbit and its contents, for determining their severity and for helping the surgeon to choose the best course of treatment.

[Diffuse cervical cellulites and descending necrotizing mediastinitis].

Objectives: To give a report on the progress in physical examination, investigations and treatment of diffuse cervical cellulites (DCC) associated with descending necrotizing mediastinitis.

Materials And Methods: A Retrospective study (1995-2005) of patients presenting DCC with mediastinitis was made. All had a cervical and thoracic Computed tomography (CT) scan.

[Imaging findings in Lemierre syndrome].

Lemierre syndrome is a septic thrombosis of the internal jugular vein with pulmonary abscesses secondary to untreated pharyngotonsillitis due to anaerobic bacteria. It occurs in young, previously healthy patients and leads to life-threatening consequences if not treated. We illustrate the value of imaging and particularly cervical and thoracic CT in a report of three recent cases.

[Sphenoid sinus mucocele of unusual aetiology and location].

Unlabelled: Mucoceles of the sphenoid sinnus are rare. 140 cases have been reported in the literature.

Purposes: We review a case and discuss: 1) pathophysiology and diagnosis of mucoceles; 2) etiologies, anatomical variants, clinical manifestations and treatment of sphenoidal mucoceles.

[Dehiscence of the anterior semicircular canal and otosclerosis: a case report].

Unlabelled: The dehiscence of the anterior semicircular canal is a new clinical entity, it is necessary to consider this when a gusher occurs during stapedial surgery.

Case Report: We report a rare case of dehiscence of the anterior canal associated with otosclerosis. This was revealed by a gusher during the initial stapedectomy.

Long-term control of vestibular schwannoma after a translabyrinthine complete removal.

[Nasopalatine canal cyst: 4 cases and a review of the literature].

Objectives: Nasopalatine cyst (NPC) is the most common epithelial and non-odontogenic cyst arising in the maxilla. It is nevertheless generally underestimated by ENT surgeons. The purpose of our report was to provide details about the pathophysiology, diagnosis and treatment of NPC.

[Methods of identification and localization of ethmoid and sphenoid osteomeningeal breaches].

The accurate localization of cerebrospinal fluid (CSF) fistula presenting as rhinorrhea is an essential requirement for successful dural repair, in order to eliminate unsuccessful surgical exploration, and to achieve a definitive closure of the osteo-dural defect. The authors report their experience in 22 patients, and propose a simplified attitude: realization of high resolution CT scan in all cases, in first choice, and a MRI with MR cysternography sequences, in second choice, in case of negative CT scan.

A persistent pharyngohyostapedial artery: embryologic implications.

A 3-year-old child was examined because of otorrhagia. CT scans showed an unusual vessel, confirmed by angiography, related to a persistent pharyngohyostapedial artery. This embryonic persistent artery associated with the normal internal carotid artery would explain the "duplication" aspect of the internal carotid artery.
