Axial positron emission tomography view. (a) Intense glucose metabolism in the left hemisphere of the cerebellum, corresponding to a hypointense and slightly enhancing area with (b) maximum diameter of 5 cm in axial T1-weighted post contrast view. (c) Axial T2-weighted fluid-attenuated inversion recovery images show the characteristic features of Lhermitte-Duclos disease: striations representing the folia of the cerebellum in association with hydrocephalus and dislocation of the fourth ventricle. (d) Axial fused positron emission tomography-magnetic resonance imaging views show the lesion with increased metabolism and intensity signal similar to that of normal grey matter.
