MRI scans prior to the operation (a–d) and after the operation (e). Each image showed a lesion (arrowheads) in the left parietal bone. A magnified clipping of the lesion is accompanied in the rectangle with each axial image (d, e). The inside of the lesion appeared with mixed intensity on T1- (b) and T2-weighted (d) images, and a part of the lumen was clearly enhanced with gadolinium contrast media (a, c). The intensity of the inside showed as high intensity on T2-weighted images after the operation (e)
