Abstract
The present multimodal diffusion tensor imaging and neuropsychological study investigated the integrity of the white matter fascicles in a 17 years-old patient diagnosed with subacute sclerosing panencephalitis (SSPE). A brief neuropsychological testing showed that word and pseudoword repetition, naming, semantic and phonological fluency, long-term memory, working memory were impaired. A review of the literature on Diffusion weighted imaging (DWI) and Diffusion Tensor Imaging (DTI) evidenced that, studies investigating the integrity of white matter in this condition being a rare disease, are very few. Significant differences (p < 0.05) were found between the fractional anisotropy (FA) values of the controls and the patient in the Superior Longitudinal fasciculus, the Inferior Longitudinal Fasciculus, the Inferior Fronto-Occipital Fasciculus, the Uncinate Fasciculus, and the Arcuate Fasciculus with lower values in the patient. No differences were found for the corticospinal tract. The number of streamlines was significantly lower in the patient, compared to controls, for the left Superior Longitudinal fasciculus, and for the left Uncinate fasciculus while for all the other fascicles, the number did not significantly differ from controls. DTI results were consistent with the patient's cognitive profile showing impairments at repetition, at tasks tapping lexical-semantics and long-term memory / retrieval. Diffusion tensor imaging results indicate that there were diffuse alterations of the degree of anisotropic diffusion along the white matter tracts distributed in posterior-anterior direction. Differently, a selective sparing of this measure was observed along the white matter tract distributed in inferior-superior direction (the corticospinal fascicle).

Abstract
BACKGROUND/AIMS This study examined correlates of the brain's neurocognitive performance among clinically and biochemically normal adult patient with hepatitis C virus (HCV). We hypothesized that anti-HCV positive individuals would demonstrate structural brain abnormalities and neurocognitive dysfunction as well as the changes in cell component and extracellular space in the white matter regions of brain in asymptomatic HCV infection by using diffusion tensor tractrography (DTT) metrics. METHODS Anti-HCV positive patient (n = 40), and healthy controls (n = 31), fulfilling inclusion criteria (incidentally detected anti-HCV positive) and able to provide informed consent were screened and recruited for the study. All these subjects and controls underwent subjective assessment of their quality of life related symptoms, neuropsychometric tests (NPT) and magnetic resonance imaging. RESULTS The patients were subjected to neuroimaging as well as psychological testing. There was no significant difference in basic laboratory parameters in these two groups. Independent t-test reveals significantly lower neuropsychological functioning as compared to healthy control. A significantly decreased FA values and myoinsitol were observed in HCV subjects on sensory, inferior longitudinal fascicules, and STR fiber bundles as compared to healthy control. Bivariate correlation analysis reveals that neuropsychological scores are significantly positive. CONCLUSION Our result show that HCV positive individuals would demonstrate structural brain abnormalities and neurocognitive dysfunction as well as the changes in cell component and extracellular space in the white matter regions of brain in asymptomatic HCV infection by using DTT metrics.

Abstract
Employing magnetic resonance diffusion tensor imaging, three-dimensional white-matter imaging and conventional magnetic resonance imaging can demonstrate the tumor parenchyma, peritumoral edema and compression on surrounding brain tissue. A color-coded tensor map and three-dimensional tracer diagram were applied to clearly display the optic-radiation location, course and damage. Results showed that the altered anisotropy values of meningioma patients corresponded with optic-radiation shape, size and position on both sides. Experimental findings indicate that the magnetic resonance diffusion tensor imaging technique is a means of tracing and clearly visualizing the optic radiation.

Abstract
Measles is an acute respiratory infectious disease caused by measles virus. Clinically, it is characterized by fever, rhinorrhea, conjunctival congestion, respiratory catarrh symptoms, oral mucosa spots, and red skin maculopapules. The patients with acute measles are the only source of its infection, who are infectious from the final 1–2 days of the incubation period to the day 5 after skin rash. Measles is commonly transmitted via respiratory droplets, with occurrence all year round but more commonly in winters and springs. Measles is the most common infectious disease in children, with strong infectivity. In recent years, the cases of measles in adults are increasing. Elimination of measles has been listed as the next objective of WHO after elimination of poliomyelitis.

Abstract
Viral infections of the central nervous system (CNS) are commonly encountered and there has been continued emergence of new neurotropic viruses which are being frequently recognized. These may present clinically as encephalitis, meningitis, encephalomyelitis, and encephalomyeloradiculitis. The clinical manifestations are usually nonspecific and diagnosis is usually based on the laboratory investigations. Imaging plays a role in its early detection and at times suggests the specific diagnosis that may help in early institution of appropriate therapy. In this review, we summarize the pathology, clinical, and imaging features of the common viral infections that affect the CNS.
