Reactivation of latent varicella zoster virus in the trigeminal ganglion with involvement of the ophthalmic division of the trigeminal nerve causes herpes zoster ophthalmicus. This is rare in children and imaging is seldom performed since the diagnosis is primarily clinical. As a result, descriptions of the associated imaging abnormalities are sparse, particularly in the paediatric literature. We present the case of a previously healthy child with herpes zoster ophthalmicus who underwent a magnetic resonance imaging scan that demonstrated enlargement and enhancement of the ipsilateral trigeminal nerve and its branches. Our aim is to highlight this finding as a potential imaging feature of herpes zoster ophthalmicus, which, to our knowledge, has not previously been reported in children.
潜伏的水痘带状疱疹病毒在三叉神经节重新激活，并累及三叉神经眼支，可导致眼带状疱疹。这在儿童中很少见，由于诊断主要基于临床，很少进行影像学检查。因此，关于相关影像学异常的描述很少，尤其是在儿科文献中。我们报告一例既往健康的患眼带状疱疹儿童，其接受了磁共振成像扫描，结果显示同侧三叉神经及其分支增粗并强化。我们的目的是强调这一发现作为眼带状疱疹潜在的影像学特征，据我们所知，此前在儿童中尚未有过报道。
