Türkiye’de insidental pulmoner nodül görülme sıklığı

Giriş: Pulmoner nodüller bilgisayarlı tomografi (BT)'de sık karşılaşılan rastlantısal bulgulardandır. Türkiye’de, rastlantısal nodül sıklığının izlenmesi ile ilgili mevcut veri bulunmamaktadır. Amacımız, ülkemizdeki rastlantısal pulmoner nodülün sıklığını ve boyutunu değerlendirmektir. Materyal ve Metod: Ocak 2015-Aralık 2016 tarihleri arasında veri tabanına kayıtlı ayaktan ve acil serviste çekilmiş tüm bilgisayarlı tomografiler retrospektif olarak incelendi. Nodüller ve özellikleri (sayı, boyut, yoğunluk, lokalizasyon) ile yaş ve cinsiyet arasındaki ilişki değerlendirildi. Bulgular: Olguların yaş aralığı 58.99 ± 16.20 yıl, 256 (%42.5)'sı kadın, 347 (%57.5)'si erkekti. Toplam 288 (%48.25) olguda 420 nodül vardı. Solid nodül 184 (%30.5) olguda mevcuttu. Bir solid nodülü olan olgu sayısı 119 (%64.7) idi. Solid nodüllerin 124 (%55.36)'ü ≥ 4- < 6 mm çapında, 64 (%28.57)'ü ≥ 6- < 8 mm çapında ve 36 (%16.07)'sı ≥ 8 mm çapında idi. Nodül sıklığı yaşla istatistiksel olarak anlamlı derecede artmıştı (p= 0.001). Sonuç: Ülkemizde insidental nodül sıklığı gelişmiş ülkelere nazaran daha yüksek bulundu.

Incidental pulmonary nodule frequency in Turkey

Introduction: Pulmonary nodules are common incidental findings oncomputed tomography (CT). In Turkey, there is no available data about thefollow-up of the frequency of incidental nodules. Our aim is to assess thefrequency and size distrubition of incidental pulmonary nodule in ourcountry.Materials and Methods: Between January 2015 and December 2016,computed tomographies, taken of all outpatient and emergency departmentthat recorded in the screening database were examined retrospectively.Nodules and their characteristics (number, size, density, localization) andrelationship between age and gender were evaluated.Results: The age range of the cases was mean 58.99 ± 16.20 years, 256(42.5%) were women and 347 (57.5%) were men. A total of 288 (48.25%)cases had 420 nodules. Solid nodule was present in 184 cases (30.5%). Thenumber of cases with one solid nodule was 119 (64.7%). There were 124solid nodules (55.36%) of ≥ 4-< 6 mm diameter, 64 solid nodules (28.57%)of ≥ 6-< 8 mm diameter and 36 solid nodules (16.07%) of ≥ 8 mm diameter. Nodule frequency increased statistically significantlywith the age (p= 0.001).Conclusion: The frequency of incidental nodule was found higher than in our country than in developed countries.
