ABSTRACT
PURPOSE:
Small breast cysts, which can be resolved by fine-needle aspiration, are often presented as hypoechoic masses on ultrasound examinations. They can be misinterpreted as benign tumors and cause unnecessary follow-ups or biopsies. The aim of this study was to find out the proportion of atypical breast cysts, which can be resolved by needle aspiration, among hypoechoic masses less than 1 cm in size and to investigate the relationship between the characteristics of a mass and its probability of being cystic.METHODS:
Between March 2003 and May 2003, we found and aspirated 119 hypoechoic masses less than 1 cm in size from 104 consecutive patients.RESULTS:
Mass size ranged from 2.5 mm to 9.8 mm, with a median size of 5.5 mm. Among the 119 hypoechoic masses, 40 masses (33.6%) were cystic and 79 masses (66.4%) were solid. Among the 40 cystic masses, 37 were completely resolved by needle aspiration, one mass was reduced to half, and the 2 remaining masses were reduced to a third of their sizes. In patients in their 20's, 11.1% of the hypoechoic masses were cystic masses, the ratios for patients in their 30's, 40's, 50's, and 60's were 11.4%, 32.0%, 76.2%, and 75%, respectively (P0.05).CONCLUSION:
Needle aspiration must be considered in small hypoechoic masses not speculated as definite solid masses.
