Description

It is our impression that Holzknecht's signs are not correctly understood by some of clinicians, but through our experience, we have found that Holzknecht's signs are most useful in diagnosis of radiolucent foreign bodies in the bronchi. Holzknecht in 1899 reported that radiological signs of bronchial stenosis were characterized by inspiratory retraction of the mediastinum and heart into the affected chest cavity.<br>The signs can only be observed by comparison of two posterior-anterior X-ray films; one at deep inspiration and the other at maximal expiration, thus confirming the difference between the two.<br>The signs can be seen at various stages of changes due to a foreign body progressing from the initial simple stenosis to valvular emphysema and further to atelectasis.
