Insights
We report a rare Creutzfeldt-Jakob disease (CJD) case. Magnetic resonance imaging showed high signal intensity in the caudate nuclei, confirmed by autopsy, a pattern not typically associated with CJD.
Area of Science:
- Neurology
- Radiology
- Pathology
Background:
- Creutzfeldt-Jakob disease (CJD) is a rare, fatal neurodegenerative prion disease.
- Typical CJD imaging findings include cortical ribboning and basal ganglia abnormalities.
Observation:
- This case highlights an unusual CJD presentation.
- Magnetic resonance imaging (MRI) revealed bilateral caudate nucleus high signal intensity four months prior to patient demise.
Findings:
- Autopsy confirmed severe caudate nucleus involvement, correlating with MRI findings.
- This specific radiologic pattern is not commonly recognized in the differential diagnosis of CJD.
Implications:
- Broadens the understanding of CJD's diverse imaging manifestations.
- Suggests considering CJD in the differential diagnosis of caudate nucleus abnormalities on MRI.
- Emphasizes the importance of integrating imaging findings with clinical and pathological data in diagnosing rare neurological disorders.
Abstract:
We have presented an unusual case of CJD in which the magnetic resonance images obtained four months before death revealed high signal intensity in the caudate nuclei bilaterally. These findings correspond to severe involvement of this region at autopsy. This radiologic pattern has not generally been included in the differential diagnosis of CJD.
