Posterior cerebral artery (PCA) dissection in children seldom is reported in the literature. This is the second report of acute PCA dissection with infarct occurring in a young child. A serial magnetic resonance angiography demonstrated a delayed and transient narrowing of the arterial caliber, which was consistent with a focal PCA dissection with delayed vascular recanalization. PCA dissection should be included in the causes of infarct in children and a thorough and serial neurovascular imaging should be considered if no cause of stroke is found.
儿童大脑后动脉（PCA）夹层在文献中鲜有报道。这是第二例关于幼儿发生急性PCA夹层伴梗死的报告。一系列磁共振血管造影显示动脉管径延迟且短暂变窄，这与局灶性PCA夹层伴延迟性血管再通相符。PCA夹层应被纳入儿童梗死的病因中，若未发现卒中病因，则应考虑进行全面且系列的神经血管成像检查。
