摘　　要：目的 分析脑内节细胞胶质瘤的CT及MRI多种影像表现,以提高对该病的认识。方法 选取经手术病理证实的26例节细胞胶质瘤患者,对其CT及MRI影像进行分析。结果 26例病灶均为单发,23例位于幕上,其中12例位于颞叶,9例位于额叶,顶叶3例,脑干及延髓各1例。实性17例,囊实性8例,1例呈完全囊性病灶。增强扫描囊性成分未见明显强化,实性部分呈轻度强化。MRS示实性部分Cho峰稍增高,NAA峰稍降低。8例另行CT检查,病灶表现为等低密度,6例出现明显钙化灶。结论 脑内节细胞胶质瘤CT及MRI的影像学表现多样,但结合多种影像学表现,可以提高对该病的诊断率。Objective To study the appearance of cerebral ganglioglioma in CT and MRI images and improve the diagnosis of this disease.Methods 26 pathologically confirmed ganglioglioma patients were recruited for the study,the CT and MRI images were evaluated.Results All 26 lesions were solitary,including 23 at supratentorial,12 in temporal lobe,9 in frontal lobe,3 cases in the parietal lobe,one in brainstem and one in medulla.17 of the lesions were solid and 8 were cystic,1 were completely cystic.In contrast enhanced images the cystic component was not significantly enhanced,the solid part was mildly enhanced.MRS in the solid part showed increased Cho peak and slightly decreased NAA peak.CT images were acquired in 8 patients ,lesions showed up as low density,6 lesions was shown with obvious calcification.Conclusion The appearance of cerebral ganglioglioma varied in CT and MRI images,therefore a combination of bothmay improve the diagnosis of the disease.
