Patient
female, 3 year(s)
 
 
  • Figure 1
    Axial T1

    An isointense lesion partially defined with hypointense cystic-necrotic areas is shown in the left posterior parietal region (arrow), and extending to the left thalamic region.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 2
    Axial T2

    Area of Interest: Paediatric; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 3
    Coronal T1

    Coronal T1 shows small areas of heterogeneous intensity that make up a mass of ill-defined limits (arrow).

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 4
    Axial FLAIR

    FLAIR sequence demonstrates mild / moderate perilesional edema predominantly in the upper parietal region (arrow), which demonstrates restriction of diffusion.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 5
    GRE

    In the posterior area of the tumor in this gradient echo sequence, there is loss of signal corresponding to areas of bleeding / calcification.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 6
    DWI (b=3000)

    On diffusion weighted sequences, hyperintensity of the perilesional oedema is demonstrated. On the ADC map the same areas are hypointense.

     
    Area of Interest: Paediatric; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 7
    ADC

    On diffusion weighted sequences, hyperintensity of the perilesional oedema is demonstrated. On the ADC map the same areas are hypointense.

     
    Area of Interest: Paediatric; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 8
    T1FS+Gd

    The lesion demonstrates moderate heterogeneous enhancement, mainly posteriorly.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;
     
     
  • Figure 9
    Spectroscopy

    Spectroscopy at TE=144ms of the tumor area shows a marked increase in the choline peak (superior arrow), with a decrease in the N-acetylaspartate peak and Cr peak (inferior arrows), (tumoral biochemical pattern).
