脑动脉瘤出血可位于蛛网膜下腔内,也可位于脑质内,CT 表现因检查时间不同而异,但既性报告颇不一致,为此作者进行了研究。应用CT 共检查了100例脑动脉瘤出血,所有病例均经血管造影或尸检证实。首次CT 检查是在出血2天内进行的,并在3～29天进行了139次重复CT 检查。首次CT 检查均有阳性所见,32例显示脑实质或隔间腔血肿,64例表现脑底池或侧裂内出血,这些表现对病变定位诊断很有帮助。余4例不具特点,仅显示幕裂孔处密度增加。CT 复查,多数脑内血肿在14～22天消失。脑底池和侧裂内出血消失较快,一般为5～9天,但也有例外,1例脑
Cerebral aneurysm hemorrhage can be located in the subarachnoid space, can also be located in the brain, CT performance due to different examination time varies, but the sexual reports quite inconsistent, for which the authors studied. A total of 100 cases of cerebral aneurysm hemorrhage were examined by CT. All cases were confirmed by angiography or autopsy. The first CT examination was performed within 2 days of bleeding and 139 repeated CT examinations were performed from 3 to 29 days. The first CT examination showed positive findings, 32 cases showed cerebral parenchyma or compartment hematoma, 64 cases of cerebral hemorrhage or penile fissure, the performance of the diagnosis of lesions is helpful. The remaining 4 cases were not characterized, showing only an increase in the density of the cut-off holes. CT review, the majority of intracerebral hematoma disappeared in 14 to 22 days. Cerebral hemorrhage and hydrocele disappeared faster, usually 5 to 9 days, but there are exceptions, 1 case of brain
