摘　　要：目的:探讨脾脏肿瘤病变的影像学诊断及鉴别。方法:经病理证实的15例脾脏肿瘤其中转移瘤3例,原发淋巴瘤4例,血管瘤5例,错构瘤2例,白血病1例。分析其CT与MRI资料,包括大小、轮廓、病灶数目、密度和边界等。结果:脾脏转移瘤为不均匀增大,病灶多发或单发边界欠清。不均匀轻度强化。原发性淋巴瘤脾脏不均匀增大,边界不清呈不规则强化。错构瘤有脂肪和钙化的特征性。血管瘤常多发,有边缘强化特征。结论:良性脾脏肿瘤性病变有一定影像表现特征,能做出正确诊断。恶性肿瘤性病变较难鉴别。Objective：To explore diagnosis and differential diagnosis of splenic tumors with CT and MKI. Methods： Fifteen cases with pathologcal comfirmed splenic tumors and examined with plain CT and contrast CT were collected. Some of them had MR films. These tumors uicluded splenic metastases （3 cases）, primary lymphoma （4 cases）, hemangiomas（5 cases）, hamartoma （2 cases）, and leukemia （1 case）. The degree of splenomegaly, contour of spleen, and the number, density,edge of tumers were analysed. Results. In patients with splenic metastases, the spleen were enlarged unhomogeneously. The tumors were multiple with indefinite edges, and the ＂target-like＂ enhancement was of the character. Uneven enlargement of spleen was commonly seen in patients of mimary lymphoma. The tumors were larger with indefinite border and ＂map-like＂ enhancement of edge was of the character. Whereas calcification and fat in tumor were the characteristic ffeatures in hamartoma. Multiple lesions were commonly seen in hemangiomas and have edge enhencement characteristies. Conclusion： The Diagnosis of splenic benign tumor can be made correctly in most patients based on features of images. Splenic malignant tumor is hard to be differential diagnosis.
