169 – Bronchoscopy in the pulmonary cavities

169 - Naked Column sign

The chest radiograph was taken without the necessary centering, as shown by the asymmetry between the clavicles and the transverse processes, generating a false image of left pulmonary retraction, (sign of the “naked column”).

A confusing destructive pattern occupies all that hemithorax in which a system of several lung cavities is hidden.
