摘要 患者女,54岁。发现右乳肿物7年,如“蚕豆”大小,无发热、疼痛,局部皮肤无红肿、破溃及渗出,双乳头无溢液,近期自觉肿物增大。专科检查:右乳内上象限2点距离乳晕3 cm可触及大小约3.5 cm×3.5 cm的肿物,质硬,活动度欠佳,边界不清,与皮肤无明显粘连。超声检查可见右乳内上象限低回声肿块,呈“分叶状”,后方回声减低,与周围组织界限不清。乳腺X线摄影显示右乳内象限分叶状高密度肿物,边界欠清,其内见斑片状钙化(图1)。乳腺MRI显示右乳内象限包块呈分叶状,T1WI呈等信号,T2WI压脂序列为低信号,DWI序列弥散受限,动态增强扫描呈不均匀明显强化,增强曲线为速升速降型(图2,3)。手术切除肿物及周围少许组织,肿物质地硬,未见包膜,界限欠清。术后标本病理结合免疫组化结果:符合骨肉瘤(图4)。
