Article Synopsis
  • Intracranial calcification (ICC) is important for diagnosing brain issues in kids, and doctors want to find the best way to see it without risking radiation from CT scans.
  • The study looked at MRI and CT scans of children with brain problems and found that MRI (especially one type called SWI) could miss ICC in some cases, but could also reduce the need for CT scans.
  • The researchers recommended starting with an MRI that uses SWI and another technique called GE, and to only do a CT scan if the MRI doesn't show ICC and more information is needed.

Objective: To assess by magnetic resonance spectroscopy (MRS) the -acetylaspartate, myo-inositol, choline, sum of glutamate and glutamine (Glx), and creatine (Cr) content in the anterior cingulate cortex (ACC)/medial prefrontal cortex (mPFC) and in the occipital cortex (OCC) (control region) in patients with functional motor symptoms (FMS) and healthy controls, and to determine whether neurochemical limbic changes as estimated by MRS correlate with FMS-related motor symptom severity, alexithymia, anxiety, depression, and quality of life.

Methods: This case-control study enrolled 10 patients with FMS and 10 healthy controls. Participants underwent MRS and were tested with the Mini-Mental State Examination, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, 20-Item Toronto Alexithymia Scale, and EuroQol 5D.

Aicardi-Goutières syndrome (AGS) is a genetically determined early onset encephalopathy characterized by cerebral calcification, leukodystrophy, and increased expression of interferon-stimulated genes (ISGs). Up to now, seven genes () have been associated with an AGS phenotype. Next Generation Sequencing (NGS) analysis was performed on 51 AGS patients and interferon signature (IS) was investigated in 18 AGS patients and 31 healthy controls.

Background: Aicardi-Goutières syndrome (AGS) is a rare genetic leukoencephalopathy related to inappropriate activation of type I interferon. Neuroradiological findings are typically characterized by white matter abnormalities, cerebral atrophy and cerebral calcification. The disease usually manifests itself during the first year of life in the form of an initial "encephalitic-like" phase followed by a chronic phase of stabilization of the neurological signs.

We studied a 9-year-old boy, affected with the Parry-Romberg syndrome, during a period of 32 months, by means of clinical evaluations and neuroradiological magnetic resonance imaging. Over this time we observed a clinical progression of the cutaneous disease without a simultaneous progression of the neurological alterations. Conventional and advanced magnetic resonance imaging techniques showed white matter alterations which proved to be stable during the follow-up.

A 56-year-old man with behavioural disorders and facial-brachio-crural right hemiparesis presented with a brain lesion studied with computed tomography, magnetic resonance imaging and brain biopsy, leading to the diagnosis of cerebral vasculitis. Hepatitis C virus (HCV) infection in a phase of activity, without cryoglobulins, was also detected. Brain biopsy, laboratory analysis and response to a specific therapy supported the diagnosis of central nervous system vasculitis that was HCV related.

Several studies report the presence of white matter lesions on brain magnetic resonance imaging in patients with migraine. The aim of our study was to detect the entity of white matter T2-hyperintensities in 90 high selected patients affected by migraine with aura, compared to a group of 90 healthy controls. We found no significant difference of incidence of white matter alterations comparing these two groups.

Background: The bilateral transfer of a motor skill is a physiological phenomenon: the development of a motor skill with one hand can trigger the development of the same ability of the other hand.

Objective: The purpose of this study was to verify whether bilateral transfer is associated with a specific brain activation pattern using functional magnetic resonance imaging (fMRI).

Methods: The motor task was implemented as the execution of the Nine Hole Peg Test.

Aicardi-Goutières syndrome is an inherited leukodystrophy with calcifying microangiopathy and abnormal central nervous system myelination. As fewer diagnostic computed tomographic (CT) scans are being performed due to increased availability of magnetic resonance imaging (MRI), there is a potential for missed diagnoses on the basis of calcifications. We review a series of patients with MRIs selected from IRB-approved leukodystrophy biorepositories to identify MRI patterns for recognition of early-onset Aicardi-Goutières syndrome and scored for a panel of radiologic predictors.

Aicardi-Goutières syndrome (AGS) is a genetic inflammatory disease. The classic neuroradiological picture mimics that of congenital infections in that Aicardi-Goutières syndrome is characterized by leukoencephalopathy, brain atrophy and intracranial calcifications. To date, bilateral striatal necrosis has not been reported in patients with AGS.

Abstract Doxycycline inhibits amyloid formation in vitro and its therapeutic efficacy is under evaluation in clinical trials for different protein conformational diseases, including prion diseases, Alzheimer's disease and transthyretin amyloidosis. In patients on chronic hemodialysis, a persistently high concentration of β2-microglobulin causes a form of amyloidosis (dialysis-related amyloidosis, DRA) localized in bones and ligaments. Since doxycycline inhibits β2-microglobulin fibrillogenesis in vitro and accumulates in bones, DRA represents an ideal form of amyloidosis where doxycycline may reach a therapeutic concentration at the site of amyloid deposition.

Following the discovery of glial fibrillary acidic protein (GFAP) mutations as the causative factor of Alexander disease (AxD), new case reports have recently increased, prompting a more detailed comprehension of the clinical features of the three disease subtypes (infantile, juvenile and adult). While the clinical pattern of the infantile form has been substantially confirmed, the late-onset subtypes (i.e.

Hypothalamic hamartoma is a rare developmental non-neoplastic malformation, often characterised by early onset gelastic seizures and later progressive cognitive and behavioural deterioration. In this case study, we have examined a child who presented with an atypical onset of benign paroxysmal gaze deviation between two to three months of age. The patient subsequently developed gelastic seizures at age 13.

Different pathologic processes (especially demyelination, hypomyelination, and combinations of these) may underlie leukoencephalopathies. Leukoencephalopathies pose a particular diagnostic problem when they occur in children. To seek associated, non-neurologic signs is of fundamental importance in hypomyelinating leukoencephalopathies, because these can help clarify the diagnostic picture.

Deposition of amyloid in the buttock is a rare complication of dialysis related amyloidosis (DRA), but this localization is even rarer in other types of amyloidoses. We report here the clinical, radiological, and biochemical features of a patient who incurred into this complication after 27 years of hemodialysis. Imaging of the amyloid deposition by magnetic resonance imaging (MRI) documents the amyloid infiltration in the muscles of the buttock region and highlights a peculiar feature of amyloid fibrils deposition in the subcutaneous fat.
