Abstract:
We describe a case report where the diagnosis of sporadic Creutzfeldt-Jakob disease(CJD) was suspected by the magnetic resonance imaging (MRI) radiologist in a 75-year-old lady who presented with rapid cognitive decline. MRI revealed cortical T2 and FLAIR(fluid attenuation and inversion recovery) hyperintensities in bilateral fronto-parietal and temporo-occipital locations and showed significant restriction on diffusion-weighted images(DWI). In this case report, we discuss the role of MRI to suspect the diagnosis of CJD in appropriate clinical settings.
Insights
Magnetic resonance imaging (MRI) can help diagnose sporadic Creutzfeldt-Jakob disease (CJD) in patients with rapid cognitive decline. Specific MRI findings, including T2 and FLAIR hyperintensities and diffusion-weighted imaging (DWI) restrictions, are key indicators.
Area of Science:
- Neurology
- Radiology
- Neuroimaging
Background:
- Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare, rapidly progressive neurodegenerative prion disease.
- Early diagnosis of sCJD is challenging due to non-specific initial symptoms.
- Magnetic resonance imaging (MRI) plays a crucial role in the diagnostic workup of suspected sCJD.
Observation:
- A 75-year-old female presented with acute cognitive decline.
- Cranial MRI revealed characteristic abnormalities in a patient with suspected sCJD.
- These included bilateral fronto-parietal and temporo-occipital cortical T2 and FLAIR hyperintensities.
Findings:
- Diffusion-weighted imaging (DWI) demonstrated significant restricted diffusion in the affected cortical areas.
- These MRI findings are highly suggestive of the diagnosis of sporadic Creutzfeldt-Jakob disease.
- The combination of clinical presentation and specific MRI patterns aids in early suspicion of sCJD.
Implications:
- MRI is a valuable non-invasive tool for suspecting the diagnosis of sCJD.
- Radiological findings can guide further diagnostic investigations and patient management.
- Increased awareness of characteristic MRI patterns can improve diagnostic accuracy for sCJD.
