脾海绵状淋巴管瘤的CT诊断与鉴别诊断(附8例分析)

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。
