| The purposes of our study were to find out characteristic ultrasonographic findings of gynecomastia and toanalyze age distribution, causative factors of gynecomastia. For these purposes, medical records of 39 malepatients with gynecomastia were reviewed and sonographic findings of 13 cases of gynecomatia were analyzed.Gynecomastia was found most commonly in teenagers and commonly in twenties. Almostly, it occured without anyevident etiology and classified as idiopathic or pubertal type. Less frequently, it occured due to drugadministration, systemic disease, or male hormone deficiency. Unilateral involvement was seen in 29 cases ; 17cases involving the left and 12 cases the right. Bilateral involvement was seen in 10 cases. Sonographically,gynecomastia appeared as hypoechoic or intermediate echoic mass with various shape in the subareolar area. onecase showed diffuse fatty breast pattern without definable mass. On sonographic evaluation, prominent nippleshould not be misinterpreted as a breast mass. For the correct diagnosis of gynecomastia, both side breasts shouldbe evaluated for comparison. |
