Characteristic pathological subtypes of MM2-cortical-type sporadic creutzfeldt–jakob disease

Classification	Prion	Pathological change	PrP deposition pattern
MM2C (lv)	M2C (lv)	Large vacuolation	Patchy-perivacuolar PrP deposits
MM2C (sv)	M2C (sv)	Small vacuolation	Synaptic PrP deposits
MM2C (lv + sv) (reported case (7))	M2C (lv) and M2C (sv)	Large vacuolation and small vacuolation	Perivascuolar and synaptic PrP deposits
MM2C (lv + sv) (This case)	M2C (lv) and M2C (sv)	Small vacuolation	Patchy-perivacuolar and synaptic PrP deposits

PrP, prion protein; lv, large vacuole; sv, small vacuole
