Childs Nerv Syst ; Finally, I will describe the potential of using resting-state fMRI as a research tool to link differences in brain connectivity patterns to neurodevelopmental disorders. In conclusion we do believe that the potential use of radiosurgery should be considered for clinically stable patients who do not require emergency treatment because of it’s high curative potential and limited range of long term complications, so long as some important good practical principles will be followed.

Neuroimaging Role and Our Experience. Di ogni paziente sono state riviste le cartelle cliniche con particolare riguardo al tipo di presentazione acuto, subacutodisturbo del movimento prevalente, tipo di evoluzione statica, progressiva e diagnosi.

Il confronto tra le caratteristiche basali dei due gruppi non ha evidenziato differenze statisticamente significative.

T2 signal intensities of the AVP were normalized to the genu of medullar corpus callosum and signal intensity ratios SIRs were obtained. All patients presented bilateral T2 hyperintense signal involving whole putamen and caudate.

Box Bethesda, MD http: He was followed for the next 30 months, with no remarkable events but some scarce epileptic seizures and imaging studies remained without visible recurrence but some small enhancing punctuate lesions scattered in both cerebral hemispheres and brainstem that progressively appeared and were interpreted as reactive radiotherapy changes. Frequent recurrence and progression in pilocytic astrocytoma in adults.


None of our patients presented bleeding after an angiographically verified AVM obliteration. Picture of the month—quiz case. Correlation analysis, conducted by using resting state fMRI data, suggests two significant differences between infants and adults: In partial third nerve palsy, different patterns may occur with or without pupillary involvement and duction deficit may not be easily observed.

Radiosurgery is an effective treatment for AVMs in the pediatric age group; if meticulously planned is pllocitico safe and bear excellent results. Therefore, it is important to know the myriad of acquired risk factors for each ages,the different clinical and radiological presentations and the best modality to identify and define the CSVT in every specific situation.
