目的:探讨乳腺纤维腺瘤样增生的超声表现及临床意义。方法:对49例经手术、病理证实为乳腺纤维腺瘤样增生,但高频声像图显示46个病灶进行了回顾性分析。结果:43个(93％)病灶呈低回声,内光点分布均匀或不均匀,3个(7％)呈中等回声;21个(45％)病灶边界清晰,19个(41％)边界欠清晰,6个(14％)部分边界清晰;3个(6％)有微钙化(超声显示2个)。所有46个病灶均无包膜。结论:大部分乳腺纤维腺瘤样增生是低回声,内部回声类似于纤维腺瘤,但均无包膜。
Objective: To investigate the ultrasound findings and clinical significance of fibrosarcoma hyperplasia of the breast. METHODS: Forty-nine patients with fibrosarcoma-like hyperplasia confirmed by operation and pathology were reviewed, but 46 high-frequency sonograms showed a retrospective analysis. RESULTS: Forty-three (93%) lesions had hypoechoic lesions with even or uneven internal light spots, three (7%) moderate echoes, 21 (45%) lesion borders were clear, and 19 (41%) borders owed. Clearly, 6 (14%) parts of the border are clear; 3 (6%) have microcalcifications (ultrasound shows 2). All 46 lesions were non-enveloped. CONCLUSIONS: Most fibroadenoma fibroid adeno-like hyperplasias are hypoechoic, and internal echoes resemble fibroadenomas, but none of them are enveloped.
