高分辨力超声对乳腺表皮样囊肿的诊断价值

目的分析乳腺表皮样囊肿的声像图特征。方法对9例乳腺表皮样囊肿患者先用二维高分辨超声仔细观察肿块位置、形态、边界、内部回声等的改变，再用彩超观察肿块内部血供情况。结果全部病例超声均发现病变，其中2例（2／9）诊断为粘稠囊性肿块，2例（2／9）被误诊为实性包块，3例（3／9）诊断为囊实混合性肿块，1例（1／9）无法判断囊性或实性，1例（1／9）仅提示大片钙化灶。多数肿块边界清楚，内部回声不均匀，肿块内部未见血流信号。结论乳腺表皮样囊肿大多数边界清晰，形态规则，内部回声不均匀，少数具有葱皮样回声，内部无血流信号，超声诊断具有重要价值。

Analysis of High-resolution ultrasound for breast epidermoid cysts

Purpose To analyze the ultrasonic appearance of epidermoid cyst. Method A total of 9 patients were involved in this study. We observed the region, shape, margin and the internal echo of the mass and the internal blood supply with CDFI with 2D High-resolution ultrasound imaging. Results There were 2 cases （2/9） with cystic-solid mixed, 2 cases （2/9） with cystic or solid and with 1（1/9） prompted large patchy calcification. Most of the mass had a distinct margin and an uneven internal echo, and there were not bloodstream signal in the mass. Conclusion When detected a breast mass with a clear margin, an uneven internal echo, few having the onion skin echo and no bloodstream signal in the mass, the possibility of epidermoid cyst should be considered.
