Inflammation occupying the pleura and the lung at the same time. Pleurisy and peripneumony existing simultaneously. Physical signs. A dull sound is yielded by percussion for a variable extent over the more dependent portions of the affected side. The loss of sound is partially modified by change of position. The respiratory murmur on auscultation is very feeble or absent inferiorly; higher up, the crepitation or bronchial respiration of pneumonia may be detected; round the root of the lung, and near the inferior angle of the scapula, egophony is generally present. There is seldom much enlargement of the affected side, or displacement of the adjacent organs, as in the case of simple chronic pleurisy.
