초록

목적: 기종격증의 MDCT에서 엽간열주위공기의 빈도와 임상특징을 알아보고자 하였다. 대상과 방법: 최근 3년간 CT에서 기종격증을 보인 90명(남: 65, 여: 25, 41세(2-84세))을 대상으로 하였다. 환자를 세군으로 나누었는데, I군은 엽간열주위공기, II군은 엽간열주위공기가 없는 기종격증, III군은 II군 중에서 기관지주위와 폐실질 내 간질성 폐기종으로 분류하였다. I군과 다른 군의 임상 데이터를 비교 분석하였다. 결과: I군의 발생률은 7.8%였다. 발생 연령에 따른 비교에서 I군과 II군 간은 유의성이 있었지만, I군과 III군 간은 유의성이 없었다(I군: 13.7세, II군: 42.9, III군: 26.4). 발생 원인 별로 보면, I군은 자발성이 가장 많았고(57.2%), II군은 외상(33.7%), 수술 후(20.5%), 자발성(9.7%) 순을 보였으며, III군은 외상(44.4%)과 자발성(33.3%)이 있었다. 자발성의 발생빈도에 따른 군간 비교에서 I군이 II군에 비해 더 높게 나왔지만(p < 0.001) I군과 III군간의 비교는 통계학적 유의성이 없었다. 자발성의 빈도에 따른 군간 비교에서 I군과 II군간은 유의성이 있었지만 I군과 III군간은 유의성이 없었다. 결론: 전체 기종격증의 CT에서 약 7.8%에서 관찰되는 엽간열주위공기는 평균 발생 연령이 13.7세로 어린 연령에 자주 생기고 대부분 자발성에 의해 발생한다.

Purpose: We wanted to evaluate the incidence and clinical features of perifissural air seen in the pneumomediastinum on CT. Materials and Methods: The study included the CT scans of 90 patients with pneumomediastinum (65 males and 25 females) and who had been treated during the recent 3 years. The ages ranged from 2 to 48 years (mean age: 41 years). The patients were divided into 3 groups, I: perifissural air (n=7), II: pneumomediastinum without perifissural air (n=83) and III: pulmonary interstitial emphysema involving the peribronchial or intraparenchymal area (n=9) of the Group II. We analyzed the clinical data and compared it between group I and the other groups. Results: Group I included 7.8% of the total cases. Age was statistically different between Group I and II, but age was not significantly different between Groups I and III (I: 13.7 years, II: 42.9, III: 26.4). A spontaneous cause was the most common (57.2%) in Group I, trauma (33.7%), postoperative occurrence (20.5%) and a spontaneous cause (9.7%) were common in Group II, and trauma (44.4%) and a spontaneous cause (33.3%) were common in Group III. The incidence of a spontaneous cause was statistically different between Groups I and II (p<0.001), but this was not significantly different between Groups I and III. Conclusion: The incidence of perifissural air seen in the pneumomediastinum on CT is 7.8%. Perifissural air is more common in the younger patients with a spontaneous cause.
