기관지경하 레이저 치료를 통해 완치한 기관내 신경초종 1예

A Case of Tracheal Neurilemmoma Which was Completely Removed by Bronchoscopic Laser Therapy

결론적으로 기관내 신경초종은 기관지 천식으로 오인되어 진단이 늦어질 수 있으나 특징적인 증상인 흡기시의 호흡곤란, 가변성 흉곽외 기도폐쇄의 소견을 보이는 폐기능 검사등으로 의심할 수있고, 기관 단층 촬영, 경부 컴퓨터 단층 촬영 및 기관지 내시경을 통해 쉽게 진단이 가능하다. 새로운 치료법으로 기관지경하 레이저 소작술로 완치될 수 있고, 이에 본원에서 경험한 1예를 보고하는 바이다.

Benign Tracheobroncheal tumor is a rare disease such as 1.9% of all tumor of pulmonary origin. Because clinical manifestation of benign tracheal tumor resembles that of broncheal asthma, these patients are usually treated in a way that used in broncheal asthma. Therefore, the diagnosis is delayed. We experienced a case of tracheal neurilemmoma that cured by bronchoscopic laser therapy. A 23-year-old woman visited our hospital because of progressing dyspnea especially during inspiration. She was treated with aminophylline and 2 agonist under the impression of bronchial asthma at a local clinic. But because the symptoms were not relieved and pulmonary function test revealed variable extrathoracic lesion, we conducted bronchoscopy and biopsy. There were $1.5{\times}2cm$ sized movable mass with stalk attached right anterior wall of bronchus. The biopsy result was neurilemmoma. Therefore we conducted bronchoscopic Laser therapy four times and the lesion disappeared in bronchoscopy and chest CT.
