5例乳腺放射状瘢痕患者的影像学表现

目的研究乳腺放射状瘢痕患者的影像学表现,以减少乳腺放射状瘢痕的误诊率和及早发现乳腺放射状瘢痕患者。方法采用病理活检和免疫组化方法来确诊5例乳腺放射状瘢痕患者,并分析乳腺放射状瘢痕的病理学表现,以研究其X线和MRI影像学表现。结果乳腺放射状瘢痕病灶呈放射状,弹力纤维变性,乳腺导管小而不规则,伴有不同程度的增生。免疫组化表明calponin分布细胞膜,腺体周围有腺上皮细胞。5例乳腺放射状瘢痕患者X线显示,癌灶周围可有钙化灶或小结节,结节周围有毛刺影。MRI中,呈类圆形结节,边缘模糊,呈等T1长T2信号,增强扫描结节呈不均匀强化。结论乳腺放射状瘢痕缺乏特异性影像学表现,但结合多种影像学改变有助于早期发现病灶。

The Image Manifestations of 5 Patients with Mammary Gland Radial Scar

Objective This study was to research the image manifestations of 5 patients with radial scars, it was in order to reduce the misdiagnosis rate of radial scars and discover the patients early. Methods The 5 patients with mammary gland radial scar were identified by the the pathological biopsy and immunohistochemistry (IHC), analyzing the pathological manifestation of mammary gland radial scar. This was to study the X-ray and MRI imaging manifestations. Results The radial scar breast lesions was radiated, the elastic fiber was degeneration, the ductal was small and irregular, following varying degrees of cattle. The IHC assay showed that calponin was located cell membrane, gland epithelial cells was appeared. The X-ray of 5 cases showed that the nodules with calcification was near the neoplastci, it was surrounded by burr. In the MRI, the neoplastici foci was circular nodules, a T1 long T2 signals, their edge was blur. The enhancement scanning showed the nodules are improved. Conclusion The radial scar was lack of specificity imaging manifestations, but it was detected early combining with a variety of imaging manifestation.
