양성 유방질환의 절제생검후 유방촬영 소견의 변화 = Mammographic changes after excision biopsy in patients with benign breast diseases

다국어 초록 (Multilingual Abstract)

We retospectively analyzed mammographic changes after excision biopsy in patients with benign breast diseases. We evaluated follow-up mammograms of 30 cases in 22 patients who confirmed as benign breast disease, pathologically. The age distribution of the patients was 29 years in the youngest and 71 years old in the oldest(mean: 45.3). The intervals between pre-biopsy mammography and post-biopsy follow up study was 20 days to 31 months(mean: 286 days).
The pathologic diagnosis of the cases were 11 fibrocystic disease patient(50%), 4 adenosis (18.2%), 3 atypical intraductal papillomatosis (8.2%) and I case of atypical ductal hyperplasia, atypical lobular hyperplasia, atrophic breast tissue, fibroadipose tissue and fibrosis.
On follow-up mammographies, 15 cases(68.2%) shouled parenchymal changes such as focally increased density, architectural distorsoin, parenchymal retraction, spiculated density 10 cases(45.5%), skin changes such as retraction or thickening but 4 cases did not show any discernible abnormality. Among cases showing parenchymal changes, 6 cases showed different configuration on different projection, which suggesting benign lesion rather than breast cancer. It was suggested that the mammographic findings after excision biopsy in benign diseases be considerably variable, and to know these findings and history of biopsy seem to be mandatory in interpretation of post-biopsy mammograms.
