螺旋CT延迟重复扫描对脑血吸虫性肉芽肿的诊断价值(附49例分析)

目的　探讨螺旋CT延迟重复扫描对脑血吸虫性肉芽肿的诊断价值及特征性表现。方法　作者回顾性分析了经手术病理和临床证实的 49例脑血吸虫性肉芽肿的螺旋CT扫描资料。结果　 90s内病灶无强化 ;第 2～ 5min内病灶开始强化 ;第 5～ 15min内病灶出现高度强化 ,并融合成团 ;第 15～ 2 0min内病灶强化逐渐消退 ;第 2 5min以后病灶无强化。结论　螺旋CT延迟重复扫描诊断脑血吸虫性肉芽肿具有特征性表现 ,正确诊断率为 10 0 %。

Diagnostic Value of Spiral CT Delay Repeated Scanning in Intracerebral Schistosomiasis(An Analysis of 49 Cases)

Objective To explore the specific features and value of spiral CT delay repeated scanning in diagnosis of cerebral schistosomiasis granuloma.Methods The spiral CT dynamil scanning material of 49 cases of intracerebral schistomiasis proved by pathology and clinic were retrospectively analyzed.Results There was no focus enhancement within ninety seconds post contialed;Focus showed a beginning enhancement was begun within the second to the fifith minutes and the peak enhancement was within the fifth to the fifteenth minutes mixed together like a ball gradually ;Focus enhancement decreased with time within the fifteenth to the twentieth minutes and disappeared after the twenty-fifth minutes.Conclusion Spiral CT delay repeated scanning had specific features in diagnosis of cerebral schistosomiasis granuloma,the diagnosis accuracy rates was 100%.
