【目的】探讨胰腺母细胞瘤的 CT 影像学特征。【方法】回顾性分析6例经手术病理证实的胰腺母细胞瘤的 CT 影像学资料。【结果】胰腺母细胞瘤好发于胰腺体尾部(4/6)，在 CT 上表现为单发，体积较大，类圆形或类椭圆形，多数边界清晰(5/6)，密度不均匀(6/6)，呈实性(4/6)或囊实性(2/6)，可伴钙化(4/6)，增强后呈不均匀轻中度强化(6/6)，可有血道或淋巴道(3/6)转移。【结论】胰腺母细胞瘤 CT 表现较具特征性，结合好发年龄及临床表现，有助于术前诊断及鉴别诊断。“,”Objective]To explore the computed tomographic (CT)features of pancreatoblastoma.[Meth-ods]CT scans were performed on 6 patients with surgically and pathologically proven pancreatoblastoma.And their imaging findings were analyzed.[Results]Most pancreatoblastomas were located in body and tail of pan-creas (4/6).Most had well-defined margins (5/6),were single,large,and round or oval.All cases had heter-ogeneous attenuation.And the consistence was solid (n =4)and cystic-solid (n =1).Other findings included calcification (4/6),mild-to-moderate enhancement (6/6)and hematogenous or lymphatic metastasis (3/6 ).[Conclusion]The CT findings of pancreatoblastoma are characteristic.In conjunctions with age of onset and clinical features,preoperative and differential diagnoses may be made.
