Brain lesions related to pregnancy are not frequent, but are potentially lethal. About half of the cases are intracerebral hemorrhage, subarachnoid hemorrhage, infarction, and venous thrombosis. Their imaging characteristics are not much different from those caused by other reasons than pregnancy, and can be relatively easily recognized. The other half of cases are encephalopathy related to pregnancy-induced hypertension, eclampsia, and other factors. Such pregnancy-related vascular encephalopathy can be grossly sorted into 3 categories: posterior reversible encephalopathy syndrome, HELLP (hemolysis-elevated liver enzymes-low platelets) syndrome, and reversible cerebral vasoconstriction syndrome. These conditions are rare, but neurosurgeons must be able to recognize them.
与妊娠相关的脑部病变并不常见，但可能致命。约一半的病例为脑出血、蛛网膜下腔出血、梗死和静脉血栓形成。其影像学特征与非妊娠原因引起的病变并无太大差异，相对容易识别。另一半病例是与妊娠高血压、子痫和其他因素相关的脑病。这种与妊娠相关的血管性脑病大致可分为3类：后部可逆性脑病综合征、HELLP（溶血-肝酶升高-血小板减少）综合征和可逆性脑血管收缩综合征。这些情况很罕见，但神经外科医生必须能够识别它们。
