Patient
male, 32 year(s)
 
 
  • Figure 1
    Plain radiographs of the lower limbs
     

    X-ray shows shaft fracture of the right femur.

     
    Area of Interest: Musculoskeletal bone; Imaging Technique: Conventional radiography; Procedure: Diagnostic procedure; Special Focus: Trauma;

    X-ray shows displaced shaft fractures of the left tibia and fibula.

  • Figure 2
    MRI images of the brain. T2WI.
     

    Axial T2 shows confluent and bilateral hyperintense lesions located in subcortical white matter and splenium of corpus callosum.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Oedema;

    Middle cerebellar peduncles are also involved.

  • Figure 3
    MRI of the brain. Axial DWI and corresponding ADC image.
     

    Axial DWI image demonstrates bilateral confluent hyperintensity lesions in periventricular and subcortical white matter of the frontal, parietal, and temporal lobes. The splenium of corpus callosum is also involved.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Diagnostic procedure; Special Focus: Oedema;

    Axial ADC image reveals restricted diffusion of the lesions, representing cytotoxic oedema.

  • Figure 4
    MRI image of the brain. Axial SWI.
     

    Axial susceptibility-weighted imaging (SWI) shows numerous petechial haemorrhages involving the subcortical and periventricular white matter and corpus callosum.

     
    Area of Interest: Neuroradiology brain; Imaging Technique: MR; Procedure: Imaging sequences; Special Focus: Haemorrhage;

    Cerebellar hemispheres, cerebellar peduncles and brain stem are also involved.
