| 中文摘要: |
| 目的 通过对45 例经病理证实的血管网织细胞瘤的影像分析,对肿瘤的影像表现及鉴别诊断做一总
结。方法 所有病例术前分别经过脑MR、CT 及DSA 检查,并对肿瘤的信号、形态大小及增强后的信号进行对比。
结果 31 例肿瘤可见囊腔,肿瘤实质部分MR、CT 可见等T1 等T2 信号或等或稍低密度影。囊性部分可见长T1 长
T2 信号或低密度信号。注药后可见肿瘤实质部分增强。41 例均可见肿瘤DSA 染色。结论 血管网织细胞瘤具有
显著特异性。应与室管膜瘤、囊性星行细胞瘤等相鉴别。 |

| Purpose 45 patients who had pathological diagnosis of hemangioblastoma are evoluated to access imaging diagnosis and differentiation. Materials All patients were examinated by MR ,CT ,DSA before the operation ,the signal ,figure both before and after contrast enhancement were collected. Results 31 cases have cysts in the tumors Solid portion of
tumors has the homogeneous signal (density) or low density in MR or CT. Cystic portion has long T1 long T2 signal or low
density. After contrast injection ,solid portion has unique enhancement . The tumors of all 41 cases have stained in DSA.
Conclusion The tumor has the significant character in diagnosis with other tumors and shald been differentiated with
medulloblastoma ,cystic astracytoma and etc. |
