  • Figure 1
    Axial FLAIR

    Axial FLAIR images showed high signal within the right side of the body and splenium of the corpus callosum.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 2
    Sagittal T2

    Sagittal T2 images showed high signal within the posteriror aspect of the body and splenium of the corpus callosum.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 3
    Axial T1 post contrast

    Axial T1 post contrast after IV gadolinium injection showed no enhancement within the lesion of the corpus callosum.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 4
    Diffusion & ADC

    Axial Diffusion images (right) showed high signal of the lesion with corresponding low signal in the ADC map (left) denoting restricted diffusion.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 5
    MR spectroscopy

    MR spectroscopic analysis of the lesion at long TE showed marked elevation of the lipid lactate peak, drop of the NAA peak and no significant choline elevation. Changes match with infarcted tissue.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 6
    Diffusion after 2 days

    Diffusion Images after 2 days of the previous images show newly developed acute infarcts along the same vascular territory of the right PCA.
