     Pediatric Radiology CasesRegion-Organ:

    Head-Brain and brain nerves  

     
     Pediatric Radiology CasesMost likely etiology:

    congenital  

     
     Pediatric Radiology CasesHistory:

    Focally symptomatic epilepsy with spike potentials left occipitally in the EEG in an almost 3 year-old girl. No persistant neurological deficits.  

     
     Pediatric Radiology CasesPathomorphology or Pathophysiology of this disease :

    The DNET is a benign mass of the cerebral cortex and usually evokes seizures.
    3 criteria should be fufilled to reach the diagnosis: Seizures before the 20th year of life., no neurological or cognitive deficit, cortical tumor.
    The tumor can be localized, however, in the basal ganglia, in the brain stem or cerebellum.
    The tumor is solidl but frequently has cystic properties. It can also be found near cortical dysplasias so that an etiology of malformation is suspected.  

     
     Pediatric Radiology CasesRadiological findings:


    MRI 1 <- view MRI 1

    MRI 1: Skull, transversal (T2-weighted slice): hyperintense mass located cortically and subcortically left occipitally.




    MRI 2 <- view MRI 2

    MRI 2: Skull, coronal (T2-weighted image)




    MRI 3 <- view MRI 3

    MRI 3 (FLAIR): Occipital mass on the left shows increased signals.




    MRI 4 <- view MRI 4

    MRI 4: (T1-weighted image): Left occipital hypointense mass.




    MRI 5 <- view MRI 5

    MRI 5: Transversal view (T1-weighted image after iv contrast): No pathologic enhancement in the mass.




    MRI 6 <- view MRI 6

    MRI 6: Coronal view (T1-weighted image after iv contrast):No pathologic enhancement in the mass.




    MRI 7 <- view MRI 7

    MRI 7: Sagittal view (T1-weighted image after iv contrast):No pathologic enhancement in the mass.




    MRI 8 <- view MRI 8

    MRI 8:(Diffusion weighted image): Decrease in signal in the left occipital mass.
