Radiopathologic correlation of LDD. (a) Photomicrograph of the surgically resected specimen (original magnification 40×) and schematic diagram of cerebellum folia, (b). Axial T2-weighted image, (c) Contrast-enhanced axial T1-weighted image. The thinned white matter, widened granular cell layer and the inner portion of the dysplastic molecular layer, which is marked as area i in a, corresponds to central core of T1 hypointensity and T2 hyperintensity on MRI (marked by triangles). The outer molecular layer and the leptomeninges, which are marked as area ii in a, corresponds to the outer thinner layer on MR images (T1 isointense, T2 iso to hypointense) (marked by white dots). An enhanced vessel runs on the cortical surface, marked by an arrow.
