星形细胞瘤的CT、MRI诊断

CT、MRI Diagnosis of astrocytoma

目的:根据星形细胞瘤CT、MRI的影像学表现,对该病进行探索研究,以便更好地诊断。方法:笔者共搜集了9例星形细胞瘤的确诊病例,根据该病的CT、MRI平扫和增强以及MRS等图像表现特点,进一步分析总结。结果:笔者通过这9例病例进行总结,其中行MRI检查7例,行CT检查2例。总体归纳如下:儿童2例,成人7例;幕上病变8例,幕下病变1例;大面积水肿有6例,无水肿或轻微水肿3例;实性者7例,囊性者2例。肿瘤实性部分不均匀强化,或环形强化,囊性部分不强化,囊壁和壁结节强化。结论:从星形细胞瘤的CT、MRI影像诊断,得出该肿瘤作为颅内最常见肿瘤之一,随分化程度不同恶性度逐级递增,界限由清楚至模糊,水肿由无到越发明显,强化亦越明显。

Objective According to the astrocytoma CT、MRI imaging findings,further study of the disease,in order to better diagnosis. Method 9 cases of confirmed cases of astrocytoma were collected. According to the disease of CT、MRI scan and enhancement and image performance characteristics such as MRS,further analysis and summary. Results 9 cases of disease was summarized,the MRI of 7 cases,the CT of 2 cases. Overall summarized as follows： Children 2 cases,7 cases of adult; supratentorial lesions in 6 cases,tentorium lesions in 3 cases; Large edema in 6 cases,no edema or mild edema in 3 cases; Real rendering in 7 cases,sac change in 2 cases. Solid tumor component uneven reinforcement,or peripheral. Cystic part not reinforce,cystic wall and wall nodule. Conclusion From astrocytoma of CT,MRI imaging diagnosis,it is concluded that change as one of the most common intracranial tumor,the tumor differentiation degree different malignant degree is increasing step by step,lion from clear to fuzzy,from no to all the more obvious edema,strengthen the more obvious.
