Objective: To examine the incidence of gynecomastia detected by chest computed tomography (CT) in the adult male population and its association with fatty liver disease, abdominal wall, and retrorenal and subcutaneous fatty tissue thickness. Methods: Chest CT scans of 1,191 patients were scanned retrospectively. One hundred fifty-eight cases with a fibroglandular tissue diameter (FGTD) of more than 2 cm were accepted as gynecomastia. Forty-five cases with FGTD less than 1 cm constituted the control group. Patterns of gynecomastia, FGTD, the subcutaneous adipose tissue thickness of breast (B-ATT), abdominal wall (AW-ATT) and retrorenal adipose tissue thickness (RR-ATT) were measured in mm. Additionally, the Hounsfield unit attenuation of the liver and spleen was obtained, and a liver-to-spleen (L/S) ratio below 0.8 was considered hepatosteatosis. The correlation between all these parameters was analysed by Kendall's Tau-b. Results: The incidence of gynecomastia was calculated as 13.2% (158/1,191), observed bilateral in 84.2% (n=133) and unilateral in 15.8% (n=25) of the cases. The dendritic pattern was the most observed type, with 57.6% (n=91) of the cases. There was a significant difference between B-ATT, AW-ATT, and RR-AAT values and gynecomastia (p<0.005), but a weak relationship was observed (r=0.137, r=0.132, r=0.098, respectively). When the study population was divided into two groups according to the L/S ratio, no significant difference was found, regarding FGTD and all the adipose tissue thickness parameters (p>0.05). Conclusion: Gynecomastia may signify visceral obesity rather than innocent hypertrophy. In clinical practice, incidental detection of gynecomastia by CT can play a useful role in case management. Keywords: Gynecomastia, computed tomography, adipose tissue thickness, visceral obesity, hepatosteatosis Amac: Eriskin erkek populasyonda toraks bilgisayarli tomografisi (BT) ile saptanan jinekomasti insidansini ve yagli karaciger hastaligi, karin on duvari, retrorenal ve deri alti yag doku kalinligi ile arasindaki iliskiyi arastirmaktir. Gerec ve Yontem: Bin yuz doksan bir hastanin toraks BT goruntuleri geriye donuk olarak tarandi. Fibroglanduler doku capi (FGTD) 2 cm'den fazla olan 158 olgu jinekomasti olarak kabul edildi. Bu kalinlik 1 cm'nin altinda olan 45 olgu ise kontrol grubunu olusturdu. Jinekomasti paternleri, FGTD, memenin deri alti yag dokusu kalinligi (B-ATT), karin on duvari (AW-ATT) ve retrorenal yag dokusu kalinligi (RR-ATT) mm cinsinden olculdu. Ek olarak, karaciger ve dalak dansitesi Hounsfield birimi cinsinden elde edildi ve karaciger-dalak (L/S) dansitesi oraninin 0,8'in altinda olmasi hepatosteatoz olarak kabul edildi. Tum bu parametreler arasindaki korelasyon Kendall's Tau-b ile istatistiksel olarak analiz edildi. Bulgular: Jinekomasti insidansi %13,2 (158/1.191) olup, olgularin %84,2'sinde (n=133) iki tarafli ve %15,8'inde (n=25) tek tarafli idi. En cok gozlenen tip olan dendritik patern olgularin %57,6'sinda (n=91) saptandi. B-ATT, AW-ATT ve RR-AAT degerleri ile jinekomasti arasinda anlamli fark (p<0,005) saptanmakla birlikte zayif bir iliski gozlendi (sirasiyla r=0,137, r=0,132, r=0,098). L/S oranina gore ayrilan iki grup arasinda FGTD ve tum adipoz doku kalinlik parametreleri acisindan anlamli fark bulunmadi (p>0,05). Sonuc: Jinekomasti, masum bir hipertrofiden ziyade viseral obezite gibi ciddi patolojileri isaret ediyor olabilir. Klinik pratikte, BT ile tesadufi olarak jinekomasti saptanmasi olgularin yonetiminde faydali bir rol oynayabilir.
