【摘要】：正患者男,61岁,因视物模糊2年、加重1个月就诊。MRI:左侧枕叶片状长T1长T2信号,周围厚壁环绕,周围可见不规则片状稍长T1稍长T2异常信号,邻近左侧侧脑室后角受压(图1A);DWI示环壁呈稍高信号,中心呈低信号(图1B);增强扫描示病灶呈厚薄不均的环形强化,强化明显,内见小片状强化影,瘤周水肿未强化(图1C)。影像学诊断:考虑星形细胞瘤(Ⅱ~Ⅲ级)。患者接受开颅肿瘤切除术,术中见肿瘤组织位于
[Abstract]:The male patient was 61 years old, with blurred vision for 2 years, aggravated by 1 month. MRI: left occipital lobes with long T 1 and long T 2 signal intensity, surrounding thick wall, irregular flake shape slightly long T 1 and long T 2 abnormal signal intensity. The compression of the posterior horn of the left ventricle (Fig. 1A) showed a slightly high signal intensity in the ring wall and a low signal intensity in the center (Fig. 1B), while the enhancement showed that the lesion showed a thin and uneven circular enhancement with obvious enhancement, small patches of enhancement, and no enhancement of peri-tumour edema (Fig. 1C). Imaging diagnosis: astrocytoma (grade 鈪，
