Abstract:
We report a 72-year-old man with Creutzfeldt-Jakob disease. He showed a progressive dementia, myoclonus, and other neurological symptoms. DNA analysis showed a normal variation of prion gene (codon 129, Met/Met: codon 219, Glu/Glu). He had periodic synchronous discharge on electroencephalogram and brain atrophy on CT scan and MRI. Diffusion images on his brain MRI revealed a marked increase in signal intensity in the caudate nuclei, putamen, and cerebral cortices. These changes may represent spongy changes of the brain and seem to be a feature of brain MRI in Creutzfeldt-Jakob disease.
Insights
This study details a 72-year-old man with Creutzfeldt-Jakob disease, highlighting key neurological symptoms and diagnostic findings. Diffusion-weighted MRI revealed characteristic signal changes in the brain, aiding in diagnosis.
Area of Science:
- Neuroscience
- Neurology
- Radiology
Background:
- Creutzfeldt-Jakob disease (CJD) is a rare, fatal neurodegenerative prion disease.
- Early diagnosis is crucial for patient management and understanding disease progression.
Observation:
- A 72-year-old male presented with progressive dementia and myoclonus.
- Electroencephalogram showed periodic synchronous discharges, and CT/MRI revealed brain atrophy.
Findings:
- Diffusion-weighted MRI demonstrated increased signal intensity in the caudate nuclei, putamen, and cerebral cortices.
- These MRI findings suggest spongiform changes, a hallmark of CJD.
Implications:
- Diffusion-weighted MRI may serve as a valuable diagnostic tool for Creutzfeldt-Jakob disease.
- Understanding these imaging features aids in differentiating CJD from other dementias.
