    A T2-weighted image (axial scan) of the brain showing a diffuse continuous dural thickening presenting with a high signal intensity.

     
    Area of Interest: unknown; Imaging Technique: T2-WI, FLAIR and contrast enhanced T1-WI of the brain at initial presentation;

    FLAIR image (sagittal scan) of the brain showing a diffuse continuous dural thickening presenting with a high signal intensity.

     
    Area of Interest: unknown; Imaging Technique: T2-WI, FLAIR and contrast enhanced T1-WI of the brain at initial presentation;

    A contrast enhanced T1-weighted image (coronal scan) of the brain showing a diffuse continuous and intense dural enhancement.

    Disappearance of the dural thickening and enhancement. An incidental finding of venous angioma is observed in the right insula.

     
    Area of Interest: unknown; Imaging Technique: Contrast enhanced T1-WI of the brain during the symptoms free period;

    Disappearance of the dural thickening and enhancement. Notice that the PGH is decreased (PGH=4.8mm) and the prepontine cistern and anterior subarachnoid space are increased.
