Auscultation over the same region should help to distinguish between these possibilities, as consolidation generates bronchial breath sounds while an effusion is associated with a relative absence of sound. Clinical symptoms are usually absent, and, when present, being characterized as dyspnea on exertion. With appropriate treatment, the consolidation usually goes away and air returns.

If the invasion or destruction of the mesenchyme of the lung is minimal, air in the lung remains within the lung cancer, resulting in a ground glass appearance on thin-section CT.
