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.
热十字面包征的特征是脑桥内出现十字形 T2 信号高信号，已被报道为多系统萎缩的特异性但非特征性表现。它反映了脑桥神经元和横行脑桥小脑纤维的变性，无论潜在的发病机制如何。在此，我们报告了一例因脑桥小脑纤维的沃勒变性导致双侧脑桥梗死后的热十字面包征病例。
