| 摘 要： | 目的:探讨淋巴管瘤不同病理学类型的磁共振表现特点以及鉴别诊断.方法:回顾性分析44例经手术病理证实为淋巴管瘤的MRI检查资料,所有病例均行矢、冠、轴三平面扫描,其中30例于MRI平扫后行常规增强扫描.以病理学所见为参照,分析各病理类型淋巴管瘤的MRI表现特点并统计分析不同病珲类型淋巴管瘤发生部位的差异.MRI征象分析包括:病变的形态、累及范围、有尤包绕血管、内部信号特点、有尤分房、分隔厚薄情况及强化特征.结果:MRI上淋巴管瘤的形态多为不规则状(38/44),边界不清(30/44),部分见血管包绕征(17/44).较大者产生占位效应.小同病理类型的淋巴管瘤发生部位的差异无显著性.与邻近肌肉组织相比,24个(54.5%)病变表现为T<1'>WI上等或高信号、T2WI上更高信号区,较具特征.囊状淋巴管瘤31例,病变内可见液-液平面,分房大,分隔细、薄,增强扫描旱轻度或无强化;海绵状淋巴管瘤7例,表现为分房多,大小不一,分隔厚或有乳头状突起,增强扫描显示分隔及乳头明显强化;血管淋巴管瘤6例,MR表现为分房大小不一,分隔厚薄不一,内未见液-液平面,增强扫描囊壁及分隔明显强化,难与海绵状淋巴管瘤鉴别.结论:淋巴管瘤不同病理学类型的MRI表现有一定特点,MRl对于鉴别囊状淋巴管瘤与其他两类较具价值,而海绵状淋巴管瘤有时难以与血管淋巴管瘤鉴别. |
