Abstract:

Lobar hemorrhage is an important subtype of cerebral hemorrhage, which is associated with cerebral amyloidosis angiopathy (CAA) and has a high incidence rate, recurrence rate and disability rate. It is of great significance to predict its clinical prognosis using plain CT. Previous studies have found that the volume and morphology (irregular morphology of edges, island sign, spot sign, finger- like projection) of cerebral hemorrhage on CT images, combined with subarachnoid hemorrhage (SAH), CT cerebral small vessel disease (CSVD) score, and CT radiomics, have certain predictive value for early hematoma expansion, neurological deterioration, and long - term poor functional prognosis, and recurrence in lobar hemorrhage. We review the predictive value of the above imaging features for the prognosis in lobar hemorrhage, providing a theoretical basis for precise prognostic stratification and individualized intervention.

摘要：

脑叶出血是脑出血的重要亚型，与脑淀粉样血管病相关，具有较高的发病率、病残率和复发率，疾病早期通过CT评估其临床预后具有重要意义。既往研究发现，CT显示的脑出血形态学特征（边缘不规则、岛征、斑点征、指状出血）、血肿体积、合并蛛网膜下腔出血、CT脑小血管病标志物评分及CT影像组学，对脑叶出血早期血肿扩大、神经功能恶化和长期预后不良、脑出血复发等具有一定的预测价值。本文基于上述影像学特征对脑叶出血预后的预测价值进行综述，以为脑叶出血的精准预后预测及个性化干预提供理论依据。
