目的:探讨弥散性神经胶质瘤的临床诊断方法。方法:对9例高度怀疑为弥散性神经胶质瘤患者实施磁共振成像(MRI)、计算机断层扫描(CT)、组织病理学诊断,观察病理表现,以病理组织活检为金标准,对比MRI、CT诊断与金标准的符合率。结果:病理组织活检显示,9例患者中,7例为弥散性神经胶质瘤,2例为颞浅动脉炎,表现为细胞密度增高,形态改变。MRI可见病灶与周围水肿分界不清,呈低信号或等信号。CT可见病灶呈浸润性生长,边界模糊不清。MRI诊断的准确率为88.89%,与病理组织活检结果比较,差异无统计学意义(P>0.05)。CT诊断的准确率为77.78%,与病理组织活检结果比较,差异无统计学意义(P>0.05)。结论:MRI及CT诊断弥散性神经胶质瘤,均无创,但MRI的准确性更高。
Objective: To investigate the clinical diagnosis of diffuse glioma. Methods: Nine patients with highly suspected diffuse gliomas were examined by magnetic resonance imaging (MRI), computed tomography (CT), histopathology and histopathology. Pathological biopsy was taken as the gold standard. MRI, CT diagnosis and gold standard coincidence rate. Results: Biopsy of pathology showed that of the 9 patients, 7 were diffuse gliomas and 2 were superficial temporal arteritis, which showed the increase of cell density and morphological changes. MRI visible lesions and the surrounding edema clear boundaries, showed low signal or equal signal. CT showed infiltration of the growth of the tumor, the boundary blurred. The accuracy of MRI diagnosis was 88.89%, which was not significantly different from the biopsy results of pathological tissues (P> 0.05). The accuracy of CT diagnosis was 77.78%, which was not significantly different from the biopsy results of pathological tissues (P> 0.05). Conclusion: Both MRI and CT have no invasive diagnosis of diffuse gliomas, but MRI is more accurate.
