张力性脑出血的CT及MRI特征分析

The Feature of CT and MRI in the Patients with Intracerebral Tension Hematoma

目的探讨脑内张力性血肿CT及MRI征象。方法经CT或MRI扫描并为手术或穿刺证实的脑内张力性血肿共24例,结合临床表现对CT和MRI影像资料回顾分析。结果张力性脑出血24例分布在基底节区居多血肿量15～75ml,具有一定张力,血肿大部分呈混杂密度或混杂信号,可出现密度或信号分层现象,具有一定特征性,周围有血管源性水肿,部分增强有包膜样强化,随访12例在发病1～2周血肿体积增大,占位效应加重,与一般高血压出血演变不一致,是诊断脑内张力性血肿的主要依据。结论张力性血肿不同于一般高血压脑出血,临床选择治疗方案也截然不同,在CT和MRI表现上具有一定特征性,结合临床可以早期诊断。

Objective to explore the sexual tension within the brain CT and MRI of haematomas signs. Methods after CT and MRI scans and for surgery or puncture confirmed the brain a total of 24 cases of sexual tension hematoma in combination with clinical manifestations CT and MRI images material review analysis. Results tension cerebral hemorrhage 24 cases distributed in the majority basal ganglia hematoma quantity 15-75 ml, have certain tension,hematoma most is mixed densities or mixed signal,can appear density or signal statified phenomenon,has certain characteristc,with surrounding vasogenic edema, part enhance have coated sample strengthening,follow-up of 12 cases in the pathogenesis of 1-2 weeks hematoma volume increases,the placeholder effect is aggravating,general with hypertension bleeding evolution is abhorrent,diagnosis of brain within the main basis of sexual tension hematoma. Conclusions tension sex hematoma is different from general hemorrhage,clinical choice treatment options are entirely different,in CT and MRI performance has certain characteristic,combined with clinical can early diagnosis,which can save patients precious time to treatment.
