【摘要】 目的：通过钼靶X线检查制定乳腺错构瘤的诊断标准。方法：报道我院1985～1995年间经手术病理证实的29例乳腺错构瘤的钼靶 X线表现。全部为女性，年龄28～64岁，平均42．4岁。右乳18例(包括右副乳2例），左乳11例。0．4～14cm大小。结果：X线表现混合型15例，脂肪型11例，致密型3例。以混合型、脂肪型最为常见，以混合型最具特征，以致密型、脂肪型最易误诊或漏诊。18例X线诊断正确，总符合率占62．00％。结论：X线检查是本病最好的方法。混杂密度改变是其 X线诊断特征。正确诊断，有利于临床手术术式的选择。更多还原

【Abstract】 Objective： To analyse the mammographic appearances of mammary hamartoma and evaluate its diagnostic criteria． Methods： Twenty－nine mammary hamartoma patients proved histologically underwent mammography． The patients＇ age ranged from 28 to 64 years with a mean age of 42．4． Results： Eighteen mammary hamartomas located in right breast and 11 in the left． The size of tumor varied from 0．4～14cm． According to the fat／parenchyma ratio， the mammographic appearance of mammary hamartomas were divided into three types． Eleven very radiolucent hamartomas were divided into fat type， 3 fairly dense hamartomas were classified as dense type and 15 hamartomas were the mixed type of adiposa and glandular tissues． The overall diagnostic accuracy rate was 62％． The mammographic appearance of the mixed type was very distinctive， and the dense or fat type could be misdiagnosed． Conclusion： X－ray examination is the best diagnostic procedure， and correct diagnosis may be beneficial for selecting the appropriate operative modality．更多还原
