| ［摘要］ 目的 探讨产后可逆性后部脑病综合征(PRES)的影像学特点及诊断价值。方法 回顾性分析4例产后PRES患者的临床及影像学资料，全部CT检查，其中2例行增强扫描。结果 PRES在产后3～28 d出现，发生于两侧额顶叶及两侧枕叶1例，左侧额顶叶1例，双侧顶叶后部2例，CT表现为脑白质区低密度改变为主，2例病灶邻近矢状窦旁出血及病灶内散在出血，随访病灶范围、数目减少、消失；2例增强扫描，病灶未见强化。结论 产后可逆性后部脑病综合征(PRES)的临床和影像学具有一定的特征性，早期做出诊断一般预后良好。 |

| Abstract: |
| ［Abstract］ Objective To investigate the imaging features and diagnosis of postpartum posterior reversible encephalopathy syndrome(PRES).Methods The clinical and imaging data of 4 postpartum PRES patients were analyzed retrospectively. 4 underwent CT, including enhancement scanning(2 cases).Results PRES occurred between 3 days and 28 days after partum. The lesions involved two sides fronto-apical lobe and end-lobe in 1 case, left fronto-apical lobe in 1case, two sides apical lobe in 2 cases.The lesions appeared mainly as low density in alba on CT, the hemorrhage by the side of longitudinal sinus adjacent to lesions or sporadic hemorrhage in lesions occurred in 2 cases.Two patients′ follow-up scan showed decreased or disappear of abnormal signals.Two cases enhancement scanning showed no enhanced lesions.Conclusion Postpartum PRES has certain clinic and imaging characteristis. Early diacrisis can improve the prognosis of PRES. |
