Bronchial cast shadow due to cellular impaction of the bronchi.
The genesis of unusual radiographic shadows by bronchi filled with tumor cells is reported. These shadows, similar to those caused by mucus or pus, are rod-like and indicate the replacement of air by water dense materials. The unifying term, "bronchial cast shadow" is proposed as the radiographic diagnostic sign.
