摘　　要：目的:通过分析脾脏海绵状淋巴管瘤的影像学表现特征,探讨其影像诊断和鉴别诊断。方法:回顾性分析8例经病理证实的脾脏海绵状淋巴管瘤的CT表现,并与其他脾脏囊性病变进行鉴别。结果:8例海绵性淋巴管瘤均为近脾门处单发囊性病灶,8例中2例病灶边界清晰,6例病灶边界模糊。所有病灶形态不规则,呈分叶状改变。囊内有分隔,壁略薄(厚度约3～5mm),囊壁及分隔略呈稍高密度,灶内可见低密度液性区。增强后动脉期、门静脉期囊壁及分隔中度强化,延迟期仍持续强化。8例患者中5例无自觉症状,经体检中发现。仅有3例出现与脾肿大相关的临床症状(左上腹胀满或轻微胀痛)。结论:脾海绵状淋巴管瘤的CT表现具有一定特征性,但需与脾脏其他囊性病变相鉴别。Objective：To discuss imaging diagnosis and differential diagnosis of splenic cavernous lymphangiomas by analyzing the CT features of them. Methods：8 patients including 3 males and 5 females with splenic cavernous lymphangioma proven pathologically were examined with CT plain and conlrast scans. Results： All cavernous lymphangioma had single cystic lesion and located in hilum of spleen. 2 were with well-defined and 6 with ill-defined margins. All cases were irregular shaped, the septation in some lesions and the wall of lesions were slight hyperdense and thin, the thickness of the wall was 3-5mm, cyst fluid was hypodense on plain CT scan. Capsule wall and septation were enhanced in arterial phase and also in portal venous phase and delayed phase. 5 patients had no clinical symptoms and the lesions were found in health examination. Three patients had just a little abdominal discomfort. Conclusion： Splenic cavernous lymphangioma have some characteristic CT features and must be differentiated with other cystic lesions of spleen.
