摘　　要：目的：分析脾淋巴管瘤的 CT 表现及 CT 与病理之间的关系。方法回顾性分析9例脾淋巴管瘤 CT 影像学特征,并与病理结果对照分析。结果9例脾淋巴管瘤中海绵状淋巴管瘤8例,囊状淋巴管瘤1例,病变含5%~50%不等的血管成分。单发性淋巴管瘤2例,多发性淋巴管瘤3例,呈圆形或类圆形囊性肿块；弥漫性淋巴管瘤4例,脾弥漫分布大小不一囊性肿块。5例单发性及多发性淋巴管瘤呈环形、细线状囊壁,分隔呈细线状、条索状；4例弥漫性淋巴管瘤囊壁及分隔呈网格状。9例脾淋巴管瘤囊腔内容物密度不均匀,CT 值10~40 HU 不等,其中3例合并砂粒状钙化。增强扫描,9例脾淋巴管瘤囊壁及分隔呈轻度强化,以延迟期强化明显；囊腔内容物呈不规则小斑片状轻度强化；囊腔内容物不随病变内血管成分增加而增强。结论CT 检查可以明确脾淋巴管瘤诊断,对指导临床治疗具有重要价值。Objective To analyze the computed tomography （CT）characteristics of splenic lymphangioma and the association be-tween CT findings and pathological results.Methods The CT characteristics and pathological findings of 9 patients with splenic lym-phangioma were retrospectively analyzed.Results There were 8 cavernous lymphangioma and 1 cystic lymphangioma.Of the 9 ca-ses,it revealed that the percentage of blood vessel elements ranging from 5% to 50% via microscope.CT found 2 cases were with single lymphangioma,3 with multiple lesions,exhibiting as round or round-like mass;4 cases were found with diffuse lymphangio-ma and different size of cystic masses distributed across spleen.Five of the 9 cases who were with single or multiple lymphangioma showed circular and thin line-like cyst wall,while the remaining 4 cases showed latticed cyst wall in CT characteristics.The content in the cysts were with uneven density in all the 9 cases with CT value ranging from 10 to 40 HU,3 of which combined with sand-like calcification.Enhancement scanning found two characteristics：（a）cyst wall and separation were mildly enhanced,especially in the delayed phase;（b）the content in the cyst presents anomalous small patchy and mild enhancement.The enhancement of the content in the cyst did not change as the increasing of blood vessel composition.Conclusion CT examination will help the diagnosis of splenic lymphangioma and is of significance in informing clinical treatment.
