摘　　要：本文分析了47例等密度硬膜下血肿的CT表现,观测的各种CT征象,发现(1)bolus增强扫描显示的血肿、血肿膜及表面移位血管;(2)中线结构的特征性偏移;(3)表面脑回聚拢内移;(4)脑灰白质界面内移;(5)侧脑室变形和脑—脑室指数变小,对等密度硬膜下血肿的诊断和鉴别诊断有重要意义。The CT manifestations of 47 ISDHs were analyzed. The CT findings of hematomas were: (1)demonstrated hematoma, membrane of hematoma and the shift of superficial cerebral vessels by means of bolus injection; (2) characterized shift of midline structure; (3) unilateral compression and gathering of the ipsilateral cortical gyri; (4) gray—white matter interface displacement; and (5)changes in size and coutour of lateral ventricles and small cranial—ventricle—index (CⅥ). These findings were very significant for diagnosis and differential diagnosis of ISDHs.
