分析28例钩体性脑动脉炎的CT所见,结果显示梗塞灶位于大脑半球,主要呈多发性和/或双侧性分布,超过半数位于供血交界区。其中7例行脑动脉造影有不同程度闭塞。钩体性脑动脉炎主要表现为大脑半球的双侧性和/或多发性,交界性的中小梗塞,可能同受累动脉很少完全闭塞或侧支循环较丰富有关。这种特点有助于鉴别诊断。6例作增强CT扫描,其中有4例呈现皮层脑回状强化,且位于无梗塞灶侧的局限性皮质萎缩处,提示可能有或发生过小梗塞。在怀疑本病时应进行增强CT扫描及血清学检查,以便及早确诊。
Analysis of CT findings in 28 cases of hooked cerebral arteritis showed that the infarction was located in the cerebral hemispheres, mainly in multiple and / or bilateral distribution, with more than half located in the donor area. 7 cases of cerebral arteriography have different degrees of occlusion. Hook cerebellar arteritis mainly for the bilateral hemispheric bilateral and / or multiple, borderline small and medium infarction, may be involved in arterial infrequently little occlusion or collateral circulation more abundant. This feature can help in differential diagnosis. Six patients underwent enhanced CT scans, of which 4 showed cortical gyrus strengthening and localized cortical atrophy at the infarct side, suggesting that there may or may not be a small infarction. In the suspected disease should be enhanced CT scan and serological tests for early diagnosis.
