We report a neonate who presented with marked hypotonia and absent suck reflex. MR demonstrated complete absence of the pons as well as absence of a basilar artery flow void. Our case exhibits features similar to those described in previous reports of pontoneocerebellar hypoplasia, but with a more severe degree of pontine involvement. The associated vascular findings suggest a vascular insult to the brain stem as the cause.
我们报告了一名表现为明显肌张力减退和吸吮反射消失的新生儿。磁共振成像（MR）显示脑桥完全缺失以及基底动脉血流信号缺失。我们的病例表现出与先前报道的脑桥小脑发育不全相似的特征，但脑桥受累程度更严重。相关的血管检查结果提示脑干血管损伤是病因。
