    Brain CT scan
     

    Unenhanced axial CT scan of the head (parenchyma window), showing a large lobulated occipital bone mass expanding into the cerebellum. Iodine injection was not performed, in case of future I-131 therapy.

     
    Area of Interest: unknown; Imaging Technique: Brain CT scan;

    CT of the skull (bone window) shows a lytic lesion of the occipital bone that involves both tables.

    Brain MRI

    Sagittal midline T2-weighted image through the brain and brainstem, showing an extradural tumour extending in height from the tentorium cerebelli to the foramen magnum.

    Area of Interest: unknown; Imaging Technique: MR venography obtained with the 2D-TOF MR venography sequence, showing no flow signal in the confluence of sinuses and in the superior sagittal sinus;

    Transverse MIP image.

    Sagittal reconstructed image showing that the superior sagittal sinus and the torcular Herophili are not occluded.

     
    Area of Interest: unknown; Imaging Technique: 3D gadolinium-enhanced MP-RAGE sequence;

    Source coronal image. This destructive skull mass compresses the underlying sinus, which explains the decreased rate of blood flow.

     
    Area of Interest: unknown; Imaging Technique: 3D gadolinium-enhanced MP-RAGE sequence;

    Axial reconstructed image. Note the remarkable enhancement of the tumour.
