摘　　要：目的：探讨成血管细胞瘤的影像学特点。材料与方法：报道１４例成血管细胞瘤的ＣＴ和ＭＲＩ所见，分析肿瘤的特点。结果：囊性肿瘤，在ＭＲＩ上表现为囊性病灶和附壁肿瘤结节；在ＣＴ上表现为该典型征象占８１．８％。混合性肿瘤３例，在ＣＴ和ＭＲＩ上表现实质性肿块、偏心性囊变和均一显著强化；后者还可见肿瘤旁和肿瘤内血管流空。结论：ＣＴ和ＭＲＩ均是诊断成血管细胞瘤的有效检查方法。成血管细胞瘤的特征性影像学表现是囊肿和突入囊内的壁结节。Objective: To explore the imaging characteristice of hemangioblastoma.Materials and Methods:CT and MRI findings in 14 cases of hemangioblastomas were reported and their characteristics were analysed.Results:Cystic tumors were all showed cystic lesion with small mural nodule in MRI. 81.8% of cystic tumors were showed this characteristic sign in CT. 3 cases of mixed type tumors were showed solid mass with eccentric cyst and solid neoplastic component enhanced markedly in both CT and MRI, in later there are vascular void both at the periphery and within the tumors in MRI. Conclusion: Both CT and MRI are efficient methods in the diagnosis of hemangioblastomas. The peculiar imaging appearance of hemangioblastomas are cystic lesion with small mural nodule and enhanced markedly.
