| 目的 观察4种脾良性肿瘤的CT表现及其鉴别诊断要点。方法 回顾性分析经病理证实的4种脾良性肿瘤的CT表现，包括血管瘤18例、淋巴管瘤3例、血管淋巴管瘤19例及错构瘤1例，观察4种肿瘤的CT表现特点。结果 脾血管瘤均为实性病灶，11例单发，7例多发；增强扫描16例表现为渐进性强化。脾淋巴管瘤均为囊性病变，增强扫描无强化。脾血管淋巴管瘤可见实性、囊性、囊实性或混合性病灶，以实性多见（n=9），常见多发病灶（n=15）；增强扫描实性病灶或病灶中的实性成分轻度强化，囊性病灶或病灶中的囊性成分无强化。错构瘤呈低密度肿块，强化方式与血管瘤类似。结论 4肿脾良性肿瘤的CT表现均有一定特征性，有助于诊断及鉴别诊断。 |

| Objective To explore CT manifestations of 4 kinds of benign tumors of spleen and the key points of differential diagnosis. Methods CT findings of 4 kinds of benign tumors of spleen were analyzed retrospectively, including 18 cases of hemangioma, 3 cases of lymphangioma, 19 cases of hemolymphangioma and 1 case of harmatoma. CT characteristics of the above 4 kinds of benign tumors of spleen were observed. Results All hemangiomas were solid lesions, including single lesion in 11 cases, multiple lesions in 7 cases of spleen; 16 cases were with typical enhancement pattern. Lymphangioma was cystic lesion without enhancement. Hemolymphangioma could be solid, cystic, solid-cystic or mixed lesions. Most of the hemolymphangiomas were multiple (n=15) and solid (n=9) lesions, mild enhancement in the solid component and without enhancement in the cystic component. The appearance of harmatoma was a hypodense tumor with enhancement pattern similar to hemangioma. Conclusion All 4 kinds of benign tumors of spleen have certain CT characteristics, which are helpful to the diagnosis and differential diagnosis. |
