Right lung: There are a fewrecent pleuritic adhesions. The lower lobe is thickly studded withmiliary tubercles, and scattered through the entire lung are suppuratingfoci like those in the left lung. At the lower border of the lower lobethere is a cheesy nodule which suggests an old tubercular lesion. Liver:There is nothing abnormal, excepting that the color is pale. The spleenis normal.
