作者报道2例相当罕见的良性脑室内肿瘤——室管膜下细胞瘤的影像特征。病例1,男性,48岁。技期间断头痛和轻微性格变化,近4个月来双下肢无力及最近表现为上肢无力。在头部MR检查之前所进行的大量有关脊髓病方面的检查均为阴性。头部MRI显示右侧脑字体部6cm×5cm×5cm肿块,并导致透明隔的中线移位和梗阻性脑积水。肿块在T_1WI(600/20)为低密度(与灰质相比),T_2WI(2800/80)和质子密度(2800/30)加权像为高密度。肿块表
The authors report two very rare cases of benign intracerebral tumors, subependymoma images. Case 1, male, 48 years old. During the technical period, her headache and minor personality changes were broken. In the past 4 months her lower extremity weakness and her recent performance were upper limb weakness. A large number of tests on myelopathy were negative before head MR examination. The head MRI showed a 6 cm x 5 cm x 5 cm mass of the right brain fonts and resulted in a transposition of the midline of the clear septum and obstructive hydrocephalus. The masses were low density (compared with gray matter) at T 1 WI (600/20), high density at T 2 WI (2800/80) and proton density (2800/30). Lump table
