MV2 type sporadic Creutzfeldt-Jakob disease (sCJD) is reported to have a long duration and marked involvement of the cerebral deep gray matter. We describe an autopsied long-surviving sCJD case of MV2. In the early stages, the patient exhibited memory impairment, attention deficit and semantic memory disorder. Diffusion-weighted MRI showed abnormal hyperintensity signals along the cerebral cortex, sparing the thalami and basal ganglia. Pathological observations included: severe spongiosis throughout the cerebral cortex, several kuru plaques and plaque-like PrP deposits in the cerebellum, with only minimal degeneration in the thalami and basal ganglia. Our case suggests that MV2 has a wide clinicopathological spectrum, which ranges from "VV2" to "MM2" type.
