【摘要】：目的归纳一组脑内节细胞瘤病例的MRI表现。材料与方法回顾性分析经手术及病理证实的5例脑内节细胞瘤MRI表现,探讨其发病部位,肿瘤形态、边界、信号及强化特点,并文献复习。结果 5例节细胞瘤中位于颞叶4例、小脑蚓部1例,肿瘤呈类圆形3例、大囊大结节状1例、不规则形1例。MRI检查肿瘤主体T1WI呈低信号(4例)或稍高信号(1例),T2WI呈稍高信号(4例)或稍低信号(1例),同时存在信号混杂(4例),CT及MRI提示含钙化3例。表现无水肿1例、轻度水肿3例、中度水肿1例。肿瘤呈轻度强化2例、中度强化3例。结论本组病例节细胞瘤MRI表现多样,但基本符合良性肿瘤特点,颞叶发生率较高,易钙化,多见于青少年,对今后临床工作中影像诊断及鉴别诊断节细胞瘤可能提供帮助。
[Abstract]:Objective to summarize the MRI findings of a group of patients with intracerebral ganglionoma. Materials and methods the MRI findings of 5 cases of intracerebral ganglioneuroma proved by operation and pathology were retrospectively analyzed. The location, shape, boundary, signal intensity and enhancement characteristics of the tumors were discussed, and the literature was reviewed. Results of the 5 cases, 4 cases were located in temporal lobe, 1 case in cerebellar vermis, 3 cases in round shape, 1 case in large cyst nodular shape and 1 case in irregular shape. MRI showed low signal intensity (4 cases) or slightly hyperintense T1WI (1 case). T2WI showed slightly high signal intensity (4 cases) or slightly low signal intensity (1 case) and mixed signal (4 cases with), CT and 3 cases with MRI indicating calcification in 3 cases). No edema was found in 1 case, mild edema in 3 cases and moderate edema in 1 case. The tumor showed mild enhancement in 2 cases and moderate enhancement in 3 cases. Conclusion the MRI findings of ganglioma in this group are various, but basically accord with the characteristics of benign tumor. The temporal lobe is more likely to be calcified, and it is more common in adolescents, which may be helpful to the imaging diagnosis and differential diagnosis of ganglioneuroma in the future.
