چکیده

The authors present two biopsy-proved cases of Creutzfeldt-Jakob disease. MR appears to be more sensitive than CT in detecting pathologic changes; signal abnormalities, when found, are predominantly within gray matter and may involve only peripheral cortex.

Diffusion-Weighted MR Imaging in Biopsy-Proven Creutzfeldt-Jakob Disease

OBJECTIVE To compare conventional and diffusion-weighted MR imaging in terms of their depiction of the abnormalities occurring in Creutzfeldt-Jakob disease. MATERIALS AND METHODS We retrospectively analyzed the findings of conventional (T2-weighted and fluid-attenuated inversion recovery) and diffusion-weighted MR imaging in four patients with biopsy-proven Creutzfeldt-Jakob disease. The sign...

Creutzfeldt-Jakob disease: comparative analysis of MR imaging sequences.

BACKGROUND AND PURPOSE MR imaging has played an increasingly important role in the diagnosis of Creutzfeldt-Jakob disease (CJD) since basal ganglia abnormalities on T2-weighted images have been described; thus, the aim of our study was to compare the value of different MR images in the diagnosis of CJD. METHODS One hundred fifty-seven patients with CJD underwent MR imaging examinations. Ninet...

Applicability of long-term electroencephalography in pre-mortem diagnosis of Creutzfeldt–Jakob disease: A case report

Creutzfeldt-Jakob disease accounts for more than 90% of all sporadic prion disease cases. The molecular MM2 genotype has been divided into cortical and thalamic subtypes based on structures involved and is characterized clinically by progressive dementia without ataxia or typical electroencephalography changes. Proposed diagnostic criteria for MM2 cortical type sporadic Creutzfeldt-Jakob diseas...

Isolated cortical signal increase on MR imaging as a frequent lesion pattern in sporadic Creutzfeldt-Jakob disease.

BACKGROUND AND PURPOSE Hyperintense basal ganglia on MR imaging support the diagnosis of sporadic Creutzfeldt-Jakob disease (CJD). Our aim was to study the frequency of patients with sporadic CJD presenting with and without characteristic basal ganglia lesions on MR imaging and to examine the corresponding patient characteristics. MATERIALS AND METHODS Fluid-attenuated inversion recovery (FLA...

"Hot cross bun" sign in variant Creutzfeldt-Jakob disease.

Disease The “hot cross bun” sign refers to pontine cruciform hyperintensity on long TR sequences, which can be observed in multiple-system atrophy, spinocerebellar atrophy types 2 and 3, and in parkinsonism secondary to vasculitis. It has not been previously demonstrated in variant Creutzfeldt-Jakob disease (vCJD), to our knowledge. A 16-year-old girl, diagnosed with vCJD at age 14 years and de...
