Abstract
Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare neurodegenerative disorder in which accumulation of a pathogenic isoform of prion protein (PrPSc) induces neuronal damage with distinct pathologic features. The prognosis of sCJD is devastating: rapid clinical decline is followed by death generally within months after onset of symptoms. The classic clinical manifestations of sCJD are rapidly progressing dementia, myoclonus, and ataxia. However, the spectrum of clinical features can vary considerably. We describe a definite, neuropathologically verified sCJD in a 67-year-old woman who initially presented with progressive stroke-like symptoms: left-sided hemiparesis and ataxia within a few days. The initial brain magnetic resonance imaging (MRI) showed bilateral cortical hyperintensity on diffusion-weighted sequences (DWI) resembling multiple ischemic lesions. Despite anticoagulation with low-molecular-weight heparin, the patient deteriorated rapidly, became dysphagic and bedridden with myoclonic jerks on her left side extremities correlating with intermittent high-amplitude epileptiform discharges on electroencephalography (EEG). Basal ganglia hyperintense signal changes in addition to cortical ribboning were seen in DWI images of a follow-up MRI. Repeated EEG recordings showed an evolution to periodic sharp wave complexes. Protein 14-3-3 was positive in her cerebrospinal fluid specimen, in addition to an abnormally high total tau level. In the terminal stage the patient was in an akinetic, mutistic state with deteriorating consciousness. She died 19 days after admission to the hospital. Neuropathologic investigation corroborated the clinical diagnosis of sCJD with spongiform degeneration and immunohistochemical demonstration of the deposition of pathologic PrPSc.Keywords
