摘要 [目的]探讨原发性乳腺恶性淋巴瘤X线、CT表现,以提高对该病的影像诊断水平.[方法]回顾性分析20例经病理证实的原发性乳腺恶性淋巴瘤的X线、CT表现(12例行X线检查,8例行CT检查).对肿瘤的部位、大小、形态、边缘、密度及强化形式进行分析.[结果]20例患者均为单侧,其中单发17例,双发3例,共23个病灶;肿瘤最大径1.7~10.2em,18个病灶呈边缘光整、类圆形或椭圆形肿块;5个病灶呈边缘不光整、不规则分叶状肿块,其中2个病灶侵犯乳腺皮肤,1个侵犯皮下脂肪间隙.密度均匀19个,不均匀4个;与正常乳腺腺体相比,X线检查病灶呈稍高密度9个,等密度4个;与正常肌肉相比,CT平扫病灶呈等密度8个,稍低密度2个,所有病灶均未见钙化及毛刺;增强后病灶轻度强化6个,中度强化4个.6例伴腋窝淋巴结肿大,肿大的淋巴结密度均匀,增强扫描呈轻度强化.[结论]边缘光整、密度均匀、轻中度强化、无明显钙化及毛刺的乳腺实质性肿块及伴密度均匀、轻度强化的腋窝肿大淋巴结为原发性乳腺恶性淋巴瘤的影像学特点,X线、CT检查可以准确显示肿瘤累及的范围,有利于临床选取恰当的治疗方案.
