Abstract

Purpose: To analyze chest radiographic findings in children infected with laboratory-confirmed novel swine-origin influenza A (H1N1) virus. Materials and Methods: Three hundred seventy-two out of 2,014 children with laboratory confirmed H1N1 infection and who also underwent a chest radiograph from September to November 2009 were enrolled in this study. Patients were divided into in-patients, out-patients, and patients with co-infections and further subdivided into with underlying disease and without underlying disease as well as age (<2 years old, 2-5 years, 5-10 years, 10-18 years old). The initial radiographs were evaluated for radiographic findings and the anatomic distribution of abnormalities. Results: The initial radiographs were abnormal in 154 (41.39%) patients. The predominant radiographic findings were peribronchial wall opacity found in 85 (22.84%) patients and hyperinflation observed in 69 (18.54%) patients. Further, 75 (71.42%) patients exhibited central predominance and the right lower lung zone was also commonly involved. There were statistically significant differences in the radiological findings between in-patient and out-patient groups. However, there were no significant differences in the radiographic findings between in-patients and the co-infection group with respect the presence of underlying disease and age. Conclusion: Initial radiographs of children with laboratory confirmed H1N1 virus were abnormal in 41.39% of cases. The common radiographic findings included peribronchial opacities, hyperinflation, lower lung zonal distribution, and central predominance.

목적: 신종인플루엔자(H1N1) 바이러스에 감염된 소아환자의 흉부방사선소견을 알아보고자 한다. 대상과 방법: 2009년 9월부터 11월까지 H1N1 바이러스로 감염된 환자 2,014명 중, 흉부방사선 촬영을 시행한 372명의 환자를 대상으로 하였다. 환자를 3가지 그룹으로 나누었는데 입원환자, 외래환자, H1N1 바이러스 이외의 다른 균과 동시 감염된 환자로 나누었고, 또한 기저질환의 유무와 나이에 따라 환자를 나누었다. 처음 시행한 흉부방사선촬영상의 영상소견, 양상, 이상 소견의 폐영역분포를 분석하였고, 기저질환이나 나이에 따른 흉부방사선소견의 차이도 분석하였다. 결과: 초기 흉부방사선촬영상에서 이상 소견은 154명(41.39%)의 환자에서 나타났다. 주된 영상소견은 기관지주위음영(85; 22.84%)과 과팽창(69; 18.54%)이었고, 대부분이 폐의 중심부를 침범하였으며(75; 71.42%) 오른쪽 아래폐영역을 침범하였다. H1N1 바이러스만 감염된 입원환자와 외래환자 사이에서 이러한 영상소견은 통계적으로 유의한 차이를 보였다. 그러나 H1N1 바이러스만 감염된 입원환자와 H1N1 바이러스 이외의 다른 균과 동시 감염된 환자 사이의 영상소견과 기저질환의 유무, 혹은 나이에 따른 영상소견에 유의한 차이는 없었다. 결론: H1N1 바이러스에 감염된 소아환자에서 초기 흉부방사선촬영상 이상소견은 41.39%에서 보였고, 기관지주위음영, 과팽창의 소견이 많았으며 대부분이 폐의 중심부, 아래 폐영역을 침범하였다.
