摘要 目的探讨乳腺钙化X线表现特点及在乳腺疾病、特别是乳腺癌诊断中的意义。方法收集乳腺钼靶X线片表现有钙化的乳腺病变共60例,均经手术病理证实。其中乳腺癌48例(浸润性导管癌35例,浸润性小叶癌8例,黏液癌3例,髓样癌2例)及良性病变12例(乳腺增生7例,慢性炎症2例,脂肪坏死2例,增生伴脂肪坏死1例)。所有病例均行钼靶X线摄影,并对照分析其钼靶X线表现。结果①恶性钙化直径多<0.5mm,表现为成簇的多形性和不均质性密集颗粒点状钙化33例,粗颗粒状钙化9例,线样或线样分支样铸型钙化6例;②良性钙化直径一般>0.5mm,形态规则,边缘清楚;③大片密集段样、区域状或成簇分布的钙化恶性多见,占85.41%(41/48),散在稀疏或粗大钙化良性病变多见,占66.66%(8/12);④60例乳腺病变钙化按密度分为高、中、低3类,分别占36.66%(22/60)、25%(15/60)和38.33%(23/60),其中高密度钙化多见于良性病变,占83.33%(10/12),中、低密度钙化恶性多见,占75%(36/48)。结论乳腺钙化是乳腺疾病重要X线征象。在乳腺癌诊断中,特别是早期癌诊断中具有重要价值。
