摘　　要：目的 :探讨CT对脾脏肿瘤的诊断及鉴别诊断价值。方法 :收集 32例脾脏肿瘤的CT资料 ,分析脾脏大小、病灶数目、密度、边界以及强化程度等表现。结果 :脾脏恶性肿瘤多表现为单发或多发低密度灶 ,边界不清 ,增强后多无强化或轻度不均匀强化 ,脾脏肿大显著 ,常伴淋巴结肿大。良性肿瘤多表现为边界清、密度均匀的低密度灶 ,脾脏不大或轻度肿大 ;血管瘤、错构瘤强化显著 ,淋巴管瘤强化不明显。结论 :CT可较好地显示脾脏大小、病灶密度、边界及CT强化程度 ,对大多数脾脏肿瘤CT可作出正确的定性诊断。Objective:To evaluate the efficacy of CT in diagnosis and differential diagnosis of splenic tumors (ST).Methods: The CT findings in 32 cases with various ST were analyzed.Results:Solitary or multiple lesions,ill-defined,lower density as compared with spleen tissue in precontrast images,no enhencement accompanied by uneven enlargement of spleen and swelling of lymph nodes were found in malignant ST. Otherwise well defined,lower density lesions with noninvolvement of lymphodes were seen in benign ST, but enhencement in hemangioma and hamartoma is remarkable.Conclusion:The benign or malignant ST could be indentified accurately by CT.[FK(WB80011?6]
