Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by segmental vasospasm and it is often accompanied by either posterior reversible encephalopathy syndrome or stroke. However, other MRI abnormalities have rarely been reported. A 28-year-old woman presented with a thunderclap headache immediately after delivery; MRI showed segmental vasoconstriction and an abnormal signal in the splenium of the corpus callosum. Neuroimaging abnormalities normalized 20 days after the first examination. Only two cases of RCVS with transient splenial lesions (TSL) have so far been reported. Both cases occurred postpartum like ours, indicating that delivery may be a trigger for the development of both TSLs and RCVS.
可逆性脑血管收缩综合征（RCVS）的特征是节段性血管痉挛，常伴有后部可逆性脑病综合征或中风。然而，其他MRI异常情况鲜有报道。一名28岁女性在分娩后立即出现霹雳样头痛；MRI显示节段性血管收缩以及胼胝体压部信号异常。首次检查20天后神经影像学异常恢复正常。迄今为止，仅报道了两例伴有短暂性胼胝体病变（TSL）的RCVS病例。这两例均与我们的病例一样发生在产后，表明分娩可能是TSL和RCVS发生的触发因素。
