Abstract

INTRODUCTION

Pulmonary nodules are common incidental findings on computed tomography (CT). In Turkey, there is no available data about the follow-up of the frequency of incidental nodules. Our aim is to assess the frequency and size distrubition of incidental pulmonary nodule in our country.

MATERIALS AND METHODS

Between January 2015 and December 2016, computed tomographies, taken of all outpatient and emergency department that recorded in the screening database were examined retrospectively. Nodules and their characteristics (number, size, density, localization) and relationship between age and gender were evaluated.

RESULT

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%). The number of cases with one solid nodule was 119 (64.7%). There were 124 solid 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 significantly with the age (p= 0.001).

CONCLUSIONS

The frequency of incidental nodule was found higher than in our country than in developed countries.

摘要

引言

肺结节是计算机断层扫描（CT）中常见的偶然发现。在土耳其，尚无关于偶然发现结节随访频率的可用数据。我们的目的是评估我国偶然发现的肺结节的频率和大小分布。

材料与方法

回顾性检查2015年1月至2016年12月期间筛查数据库中记录的所有门诊和急诊科的计算机断层扫描。评估结节及其特征（数量、大小、密度、位置）以及年龄与性别的关系。

结果

病例的年龄范围平均为58.99±16.20岁，女性256例（42.5%），男性347例（57.5%）。共有288例（48.25%）病例有420个结节。实性结节存在于184例（30.5%）中。有一个实性结节的病例数为119例（64.7%）。直径≥4-<6mm的实性结节有124个（55.36%），直径≥6-<8mm的实性结节有64个（28.57%），直径≥8mm的实性结节有36个（16.07%）。结节频率随年龄增长有统计学显著增加（p=0.001）。
