Hot Cross Bun Sign Following Bilateral Pontine Infarction: A Case Report
نویسندگان
چکیده
The hot cross bun sign is characterized by cruciform T2 signal hyperintensity in the pons and has been reported to be a specific but not pathognomic for multiple system atrophy. It reflects degeneration of pontine neurons and transverse pontocerebellar fibers, regardless of the underlying pathogenic process. Here, we report a case of hot cross bun sign following bilateral pontine infarction due to Wallerian degeneration of the pontocerebellar fibers.

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013203447 DESCRIPTION Though uncommon, bilateral middle cerebellar peduncle (MCP) hyperintensities have been reported following pontine infarcts, in Wilson disease (WD) and due to other aetiologies. In WD, the ‘face of the giant panda’ sign, internal capsule hyperinten...

We report a 25-year-old young man presenting with cognitive decline, pancerebellar features, spastic quadriparesis, bilateral cataract (operated) and tendo-Achilles swelling (xanthoma). The CT of the head showed bilateral cerebellar hypodensities. There were bilateral cerebellar hypointensities involving dentate nuclei on T1-weighted images with corresponding hyperintensities on T2-weighted MRI...

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...

OBJECTIVE To investigate whether proton density-weighted imaging can detect the "hot cross bun" sign in the pons in multiple system atrophy with predominant cerebellar ataxia significantly better than T2-weighted imaging at 3T. METHODS Sixteen consecutive patients with multiple system atrophy with predominant cerebellar ataxia according to the Consensus Criteria were reviewed. Axial unenhance...
