目的总结胶质母细胞瘤CT平扫及增强扫描的影像学表现。方法选择2011年1月至2015年11月收治经手术病理证实的胶质母细胞瘤患者58例,均进行CT平扫及增强扫描,对胶质母细胞瘤CT平扫及增强扫描的表现进行总结。结果病理结果显示胶质母细胞瘤55例,间变性星形细胞瘤3例。肿瘤部位:颞叶25例,额叶21例,颞顶叶7例,顶叶4例,枕顶叶1例。CT平扫表现为高密度病灶,内部可见囊变坏死,形态多不规则、边界不清、瘤周水肿明显。增强扫描主要为花环状或环状明显强化、厚薄不均。结论胶质母细胞瘤CT平扫及增强扫描具有明显特征,平扫表现为形态不规则、边界不清、病灶周围水肿明显,增强扫描多出现花环状或环状明显强化、厚薄不均,多数患者可做出正确术前诊断。
Objective To summarize the imaging findings of glioblastoma CT scan and enhanced scan. Methods Fifty-eight patients with glioblastoma confirmed by surgery and pathology from January 2011 to November 2015 were enrolled in this study. Both CT scan and enhanced scan were performed on CT scan and enhanced scan of glioblastoma to sum up. Results The pathological results showed that there were 55 cases of glioblastoma and 3 cases of anaplastic astrocytoma. Tumor site: 25 cases of temporal lobe, frontal lobe in 21 cases, temporal parietal lobes in 7 cases, parietal lobe in 4 cases, and occipital parietal lobe in 1 case. CT scan showed high-density lesions, cystic degeneration can be seen inside, irregular shape, border is unclear, peritumoral edema. Enhanced scan mainly garland or ring significantly strengthened, uneven thickness. Conclusions CT glioblastoma CT scan and enhanced scan has obvious features, the performance of the irregular scan, the border is unclear, obvious edema around the lesion, enhanced scan appear more garland or ring significantly enhanced, uneven thickness, Most patients can make the correct preoperative diagnosis.
