目的　通过临床病例分析了解原发性脾脏良性肿瘤的临床特点。方法　总结 1990年 1月至 2 0 0 0年12月期间收治的 13例原发性脾脏良性肿瘤病例 ,对其临床表现、影像学特点和疗效进行分析。结果　原发性脾脏良性肿瘤的临床表现无特异性 ,影像学特点为脾实质内单发或多发的实性结节 ,脾脏切除术疗效好。结论　影像学检查是诊断原发性脾脏良性肿瘤的主要依据 ,术前不易与恶性肿瘤区别 ,治疗应首选脾脏切除术 Objective To understand the clinical features of primary spleen benign tumors through clinical case analysis. Methods From January 1990 to December 2000, 13 cases of primary benign splenic tumors were treated, and their clinical manifestations, imaging features and therapeutic effects were analyzed. Results The clinical manifestations of benign primary spleen tumors were nonspecific. The imaging features were single or multiple solid nodules in the splenic parenchyma. The splenectomy was effective. Conclusion Imaging examination is the main basis for the diagnosis of benign tumors of primary spleen, preoperative and malignant tumors is not easy to differentiate, the treatment should be the preferred splenectomy
