影像表现

乳腺钼靶：双乳见散在纤维腺体样密度；左乳4点位见一分叶状肿物，大小约35x0x36mm，低回声，边缘成角。肿物可触及，并见乳头内陷及皮肤增厚。左乳点位见一不规则低回声卵圆形肿物，大小约x10x3mm，内见钙化，可能为乳腺内淋巴结。左乳9点位见一不规则低回声肿物，大小约17xx18mm，后方见声影，与乳腺钼靶上中部的结构扭曲相对应。钼靶及超声均可见左侧腋窝增大淋巴结。

影像表现

乳腺钼靶：常表现为较大肿物，乳腺不对称，结构扭曲，钙化，皮肤增厚，皮肤溃疡，乳头内陷，密实的腋窝淋巴结。

超声：常表现为较大肿物，弥漫浸润性回声，弥漫阴影，皮肤及皮下组织增厚、水肿，淋巴结肿大。受累的淋巴结表现为淋巴门脂肪消失，中心坏死，偏心性皮层萎缩。彩色多普勒超声示高级别肿瘤血供丰富。

MRI：肿瘤表现为多发病灶，可见胸大肌、肋间肌、皮肤及乳头受累。
