| 摘 要： | 目的:研究基底节区生殖细胞瘤的常规MRI及质子磁共振波谱(1H-MRS)表现.方法:对6例经活检或手术病理证实的生殖细胞瘤的MRI和1H-MRS表现进行回顾分析.结果:6例基底节区生殖细胞瘤均为男性,病灶T1WI多呈低或等信号,T2WI呈高信号.增强后病灶不均匀斑点、片状及环状强化.1H-MRS表现为胆碱(Cho)峰升高,肌酸(cr)降低,氮乙酰天门冬氨酸(NAA)明显降低.结论:基底节区生殖细胞瘤的MRI影像表现具有一定特点,结合1H-MRS,可以提高生殖细胞瘤的诊断水平.

| Abstract: | Objective:To study the MRI and 1H MRS findings of basal ganglia germinoma.Methods:Of 6 cases with biopsy or surgery and pathology proved germinomas arising from basal ganglia,the MRI and 1H MRS findings were analyzed retrospectively.Results:All 6 patients with germinoma arising from basal ganglia were male.The tumor showed hypo-or iso-intensity on T1 weighted images and hyper-intensity on T2 weighted images.After contrast enhencement,heterogeneous spotty,patchy and ring-like enhancement was showed.On 1H MRS,promiment choline (Cho) peak,low creatine (Cr) and N acetylaspartate (NCC) peaks were displayed.Conclusion:Characteristic MRI findings could be revealed in germinomas arising from basal ganglia.When combined with 1H MRS,the diagnostic accuracy could be improved. |
