目的：加深对乳腺纤维腺瘤的认识，以提高Ｘ线诊断准确率。材料与方法：２３例３５个乳腺纤维腺瘤均经手术病理证实，均摄双侧乳房轴、斜位像，１例加照病灶局部点压片，分析其Ｘ线征象，并与临床、手术病理对照。结果：２０个病灶边界清晰锐利，１０个有部分清晰边界，１个斜位边界清晰锐利而轴位不清，４个界限不清，均为中等密度，２个有钙化；圆形、类圆形２３个，分叶状９个；大小界于１０～６０ｃｍ之间。结论：大多数乳腺纤维腺瘤Ｘ线可做出明确诊断，不典型者需结合临床及手术病理确诊。
Objective: To deepen the understanding of breast fibroadenoma in order to improve the diagnostic accuracy of X-ray. MATERIALS AND METHODS: Twenty-three cases of 35 fibroadenoma of the breast were confirmed by surgery and pathology. The bilateral breast axis and oblique images were taken, and 1 case of local fibroadenoma with focal lesion was performed. The X-ray signs were analyzed and compared with clinical, Pathological control. Results: The borderline of the 20 lesions was clear and sharp. Ten of them had some clear boundaries. One oblique boundary was clear and the axis was unclear. The four boundaries were unclear. Both of them were medium density and two had calcification. Shaped 23, lobulated 9; the size of the border in 1 0 ~ 6 0cm between. Conclusion: Most breast fibroadenoma X-ray can make a clear diagnosis, atypical cases need to be combined with clinical and surgical pathology confirmed.
