摘要

肺陷落(lung collapse)可因許多原因造成，如腫瘤阻塞或壓迫支氣管造成之肺陷落及一些良性病變，如慢性炎症等所造成之肺陷落等。傳統的胸部攝影往往只能判斷肺陷落的位置，而很難診斷造成肺陷落的原因，而電腦斷層攝影對於肺陷落的診斷價值除了能判斷肺陷落的位置，並可經由此檢查了解造成肺陷落的機轉，進而診斷造成肺陷落之原因。三軍總醫院放射線部自民國71年10月至民國74年9月，電腦斷層診斷肺陷落58例，因腫瘤造成者有34例，其中支氣管內病灶8例，腫瘤擠壓支氣管引起者23例，腫瘤侵犯整個肺葉引起者3例；非腫瘤所造成之肺陷落或肺膨脹不全(atelectasis)24例，其中肋膜積液所引起者11例，炎性病灶引起者12例，放射治療引起者1例，本文就肺陷落之電腦斷層發現，進而分析與研究肺陷落之致病原因。

The difference between conventional chest film and high resolution computed tomography in diagnosis of lung collapse was that the latter may clearly identify the anatomic position and the causes of the collapsed lung. Fifty-eight cases of collapsed lung were found by computed tomography from October 1982 to September 1985 in our hospital. Thirty four cases were caused by tumor lesions which include 8 cases of endobronchial tumor, 23 cases of tumor compress to the bronchus and 3 cases of lobar tumor, Another 24 cases of lung collagse were caused by inflammatory process which include 11 cases of passive atelectasis, 12 cases of cicatrization atelectasis and 1 case of radiation atelectasis. Besides the location and causes of collapsed lung, high resolution computed tomography can evaluate the degree of collapsed lung and the extent tumor growth which cause collapse of lung.
