The actual role of 18F-FDG PET/CT in evaluating primary brain lymphoma is still an open issue. Brain lymphoma usually show elevated 18F-FDG uptake, often higher than other brain tumors or inflammatory processes, but the metabolic behavior of this lymphoma is not still understood. Our aim was to investigate the particular metabolic behavior of this lymphoma. Forty six patients (21 female, 25 male) with histologically-confirmed brain lymphoma who underwent 18F-FDG PET/CT from vertex to the mid-thigh for initial staging were retrospectively evaluated...

Surgery in and around eloquent brain structures poses a technical challenge when the goal of surgery is maximal safe resection. Magnetic resonance imaging (MRI) has revolutionized the diagnosis and treatment of neurological disorders, but tractography still remains limited in terms of utility because of the requisite manual labor and time required combined with the high risk of bias and inaccuracy. Automated whole brain tractography (AWBT) has simplified this workflow, overcoming historical barriers, and allowing for integration into modern neuronavigation...

OBJECTIVE: To determine if a brain MRI scan in patients with a diagnosis of migraine, who insist on the performance of imaging, is of more benefit in detecting clinically significant unsuspected structural abnormalities than would be expected by chance. METHODS: This prospective, observational, single center study was performed from January 1, 2010 to December 31,2012 and included 100 subjects with a diagnosis of migraine and a normal neurologic exam. A brain MRI scan was performed on all patients, solely at their request, to detect an unsuspected clinically significant structural lesion...

RATIONALE: Holmes' tremor is an uncommon neurologic disorder following brain insults, and its pathogenesis is undefined. The interruption of the dento-rubro-thalamic tract and secondary deterioration of the nigrostriatal pathway are both required to initiate Holmes' tremor. We used nuclear medicine imaging tools to analyze a patient with concurrent infarction in different zones of each side of the thalamus. Finding whether the paramedian nuclear groups of the thalamus were injured was a decisive element for developing Holmes' tremor...

CLINICAL PROBLEM: Intracerebral cysts are common findings in imaging of the neurocranium and are not always clinically significant. The pathological spectrum of intracerebral cysts is, however, very broad and in addition to incidental findings includes developmental disorders, malformation tumors, primary and secondary neoplasms and infectious etiologies, such as cerebral abscess formation, cysticercosis or residuals after congenital cytomegalovirus infections. Intracerebral cystic defects may be caused by inflammatory central nervous system (CNS) diseases, such as multiple sclerosis as well as by mitochondriopathies, leukodystrophy, electrolyte disturbances or osmotic demyelination syndrome or brain infarctions, e...

BACKGROUND AND OBJECTIVE: Natalizumab-associated progressive multifocal leukoencephalopathy (NTZ-PML) patients may show imaging signs suggestive of inflammation at diagnosis ('inflammatory PML'), reminiscent of PML-immune reconstitution inflammatory syndrome (PML-IRIS). We investigated the imaging characteristics of inflammatory NTZ-PML lesions and PML-IRIS to determine differentiating and overlapping features. METHODS: We scored the presence, localisation and pattern of imaging characteristics of inflammation on brain MRI scans of inflammatory NTZ-PML patients...

Hypsarrhythmia in West syndrome, although hard to define, is characterized by chaotic and disorganized electrical activity of the brain and is often regarded as a generalized EEG pattern without any localization value. Using event-related spectral perturbation (ERSP), we tried to determine the brain dynamics during hypsarrhythmia. Routine 1-h scalp EEGs were retrieved from 31 patients with infantile spasms and 20 age-matched controls. Using the EEGLAB toolbox of MATLAB 2015b, the ERSPs of fast oscillations (FOs; 20-100 Hz) of selected channels were analyzed and compared among groups according to their MRI lesions...

A 12.6-year-old girl presented with a 2-month history of headache, recurrent vomiting and 5 kg weight loss. She had been receiving recombinant human growth hormone (rhGH) replacement therapy at a dose of 0.035 mg/kg for the past 10 months, due to short stature. Investigations before initiating rhGH, including brain MRI, had been normal. Physical examination revealed a nystagmus and a mildly elevated arterial blood pressure. Brain MRI revealed a lesion in the posterior aspect of the medulla oblongata, adjacent to the foramen of Magendie...

Fibrinogen is a protein that plays a key role in blood coagulation and thrombosis and it is involved in several inflammatory processes; in multiple sclerosis (MS) may be related with blood-brain barrier (BBB) disruption. We analysed the relationship between plasma fibrinogen levels and the presence of active lesions on magnetic resonance imaging (MRI) during relapses of multiple sclerosis (MS) and clinically isolated syndrome (CIS) patients. METHODS: We collected data of patients admitted to a tertiary-care hospital with relapse of MS and CIS from 2008 to 2013 and we analysed the relation between plasma fibrinogen levels (normal: 200mg/dl-417mg/dl) and the presence of active lesions on brain or spinal MRI...

INTRODUCTION: Acute disseminated encephalomyelitis (ADEM), an immune mediated inflammatory disease is common in children. The profile and immediate outcome of children hospitalized with ADEM is scarce in the available literature. OBJECTIVES: We aimed to study the clinical profile of children with ADEM and to look for prognostic factors for outcome at discharge from hospital METHODS: We chose a retrospective cohort study of all children diagnosed with ADEM at our institution between January 2006 and December 2015, and they were evaluated, after excluding other diagnoses when they were summoned for a follow up visit...

BACKGROUND: Diffuse axonal injury (DAI) on MRI has been associated with poor functional outcome after moderate-severe traumatic brain injury (msTBI). Yet, DAI assessment with highly-sensitive MRI-techniques is unfeasible in the acute trauma setting, and CT remains the key diagnostic modality despite its lower sensitivity. We sought to determine whether CT-defined-hemorrhagic-DAI (hDAI) is associated with discharge and favorable 3-and 12-month functional outcome (Glasgow Outcome Score ≥4) after msTBI...

Thiamine is a water-soluble vitamin, which participates in several vital metabolic pathways involved in energy metabolism and neurotransmitter synthesis of mammals. In companion animals thiamine deficiency is classically associated with signs of diffuse encephalopathy and lesions on brainstem nuclei and mesencephalic colliculi evident on magnetic resonance imaging. This paper describes a novel clinical presentation in a thiamine-deficient dog showing multifocal, central and peripheral nervous and cardiovascular system alterations...

REVIEW
Alberto Gajofatto
Siponimod (BAF312) is a synthetic molecule belonging to the sphingosine-1-phosphate (S1P) modulator family, which has putative neuroprotective properties and well-characterized immunomodulating effects mediated by sequestration of B and T cells in secondary lymphoid organs. Compared to fingolimod (ie, precursor of the S1P modulators commercially available for the treatment of relapsing-remitting [RR] multiple sclerosis [MS]), siponimod exhibits selective affinity for types 1 and 5 S1P receptor, leading to a lower risk of adverse events that are mainly induced by S1P3 receptor activation, such as bradycardia and vasoconstriction...
