Sporadic Creutzfeldt-Jakob disease: Brain MRI lesion features from 2 cases reports

Abstract

Sporadic Creutzfeldt-Jakob disease (sCJD) is an uncommon prion disease, also a fatal degenerative brain disorder. We aimed to illustrate 2 clinical cases, a 60-year-old female and a 57-year-old male, who came to the hospital due to rapidly progressive cognitive decline. A 1.5T brain MRI in both patients detected cortical and basal ganglia signal abnormalities with diffuse, asymmetrical features. The patient underwent electroencephalography and cerebrospinal fluid tests, which showed abnormal waves and a positive 14-3-3 protein test in the CSF samples of both patients. According to the 2018 US Centers for Disease Control and Prevention (CDC) diagnostic criteria, we finally diagnosed these patients with sCJD.
