Anxiety disorders are highly prevalent and disabling but seem particularly tractable to investigation with translational neuroscience methodologies. Neuroimaging has informed our understanding of the neurobiology of anxiety disorders, but research has been limited by small sample sizes and low statistical power, as well as heterogenous imaging methodology. The ENIGMA-Anxiety Working Group has brought together researchers from around the world, in a harmonized and coordinated effort to address these challenges and generate more robust and reproducible findings.

Only few studies have reported muscle involvement in spinal muscular atrophy using muscle MRI but this has not been systematically investigated in a large cohort of both pediatric and adult patients with type 2 and type 3 spinal muscular atrophy. The aim of the present study was to define possible patterns of muscle involvement on MRI, assessing both fatty replacement and muscle atrophy, in a cohort of type 2 and type 3 spinal muscular atrophy children and adults (age range 2–45 years), including both ambulant and non-ambulant patients.

Background: Malignant Intramedullary Spinal Cord Tumor are a relatively uncommon entity affecting patients whose prognosis is quickly and relentlessly dismal. Since the ‘50s Spinal Cordectomy’ has been advocated for the surgical management of these conditions, but to date, no standard operative protocol has been reported yet. Objective: Although apparently “easy”, burdened by virtually no further risk for the neurological function in paraplegic or severely paraparetic patients, SCt conceals notable pitfalls and surgical problems that are to date not yet completely discussed.

Infective endocarditis (IE) is a serious cardiac condition, which includes a wide range of clinical presentations, with varying degrees of severity. The diagnosis is multifactorial and a proper characterization of disease requires the identification of the primary site of infection (usually the cardiac valve) and the search of secondary systemic complications. Early depiction of local complications or distant embolization has a great impact on patient management and prognosis, as it may induce to aggressive antibiotic treatment or, in more advanced cases, cardiac surgery.

Multiple sclerosis is one of the most common chronic neurological diseases affecting the central nervous system. Lesions produced by the MS can be observed through two modalities of magnetic resonance (MR), known as T2W and FLAIR sequences, both providing useful information for formulating a diagnosis. However, long acquisition time makes the acquired MR image vulnerable to motion artifacts. This leads to the need of accelerating the execution of the MR analysis.

Lateral neck masses may be due to congenital, infectious, or malignant disease. Sometimes, the mass can be the only sign of an asymptomatic cancer. A correct clinical approach and the differential diagnosis are the key points for a correct diagnosis.

Background: Diagnosis of central or peripheral facial palsy (FP) is traditionally based on clinical evaluation. This study aims at investigating the relationship between clinical evaluation of FP and lesion location as visible on Magnetic Resonance Imaging (MRI) in patients with Multiple Sclerosis (MS) for the purpose of adding supporting evidence to the diagnosis of central or peripheral FP in these patients.

We investigated if loop characteristics correlate with audio-vestibular symptoms or hemifacial spasm in patients with a vascular loop in the root entry zone (VII and VIII) and in the internal auditory canal.

Background The presence of white matter hyperintensities (WMHs) can impact on normal brain function by altering normal signal transmission and determining different symptoms.
Aim To evaluate the relationship between the presence of brainWMHs and the scores of speech perception test (SPT) in a sample of normal-hearing patients under 70 years of age.

BACKGROUND Documentation of disease activity in patients affected by Crohn's disease (CD) is mandatory in order to manage patients properly. Magnetic resonance imaging (MRI) is considered the reference cross-sectional technique for the assessment of CD activity. Among MRI findings, layered pattern (LP) of contrast enhancement seems to be one of the most significant signs of severe disease activity; however, it has also been associated with chronic disease and mural fibrosis.
