目的 :总结肝脏少见肿瘤的CT特点 ,以提高其CT诊断水平。材料和方法 :回顾性分析 9例肝脏少见肿瘤的临床、病理及CT特点。结果 :其CT特点包括 :( 1) 3例肝肉瘤类肿瘤体积均较大 ,易坏死囊变 ,发展快 ;其中胚胎性肉瘤内见分隔状软组织影 ;( 2 ) 1例肝类癌内见钙化影 ;( 3 ) 1例肝非何杰金氏淋巴瘤肝内多个类圆形低密度肿块 ,环形增强及腹膜后淋巴结肿大 ;( 4 ) 1例肝血管淋巴管瘤病见多房囊性低密度及纤维分隔影 ,周边见斑点状、条状钙化 ,肿瘤周围及其内纤维分隔明显增强 ;( 5 ) 3例肝血管平滑肌脂肪瘤增强后均见中心斑点状增强血管影。结论 :典型CT表现结合临床其它资料 ,可提高肝脏少见肿瘤CT诊断的准确性。
Purpose: To improve the diagnostic level by analyzing the CT features of rare hepatic tumor. Materials and Methods: The clinical, pathologic and CT imaging features of 9 cases of rare hepatic tumor were reviewed retrospectively. Results: The CT features were discussed. (1) There was 3 case of hepatic sarcocarcinoma with larger volume, cystic necrosis areas and fastly development, 1 case of hepatic undifferentiated embryonal sarcoma with multiplicate hyperdense septations of variable shapes; (2) 1 case of hepatic carcinoid had calcified foci;(3)1 case of no-Hodgkin's lymphoma had multioplicate、hypodense、like-circular lesion and enhancement margins, with multioplicate enlargement lymophatic nodules in retroperitoneum; (4)1 case of angio-lymphangioma had multioplicate cyst areas and septation of variable shapes, with spot and branch calification on the margins of lesion. The septation of variable shapes was marked enhanced; (5) 3 case of hepatic angiomyolipomas had the central enhanced vascular imaging after injection contrast medium. Conclusion: The typical CT findings, combined with clinical and others information, can lead to a correct diagnosis preoperatively in rare hepatic tumors.
