Three such cases have comeunder the writers observation, whichwere either confirmed by autopsy ormicroscopic sections from material ob-tained by lung puncture. One of the most difficult differentialdiagnoses may be in the differentiationbetween lower-lobe pneumonia and fluid,or the simultaneous existence of both.The upper border of a pleural effusion structures are usually displaced in fluid,but, as has been said, that is not an infalli-ble sign, for either no displacement at allmay be present, or it may be so slight asto be indeterminate. Under certain condi-tions, therefore, the diflerential diagnosisbetween lower-lobe pneumonia and fluidbecomes very difficult. A method whichwe have used occasionally, and have foundmost useful in the differentiation of thetwo conditions will be briefly outlined(Fig. 16). Since the upper bounding plane

It is truethat the costophrenic angle is obliteratedin fluid and is usually well aerated duringthe acute stage of lower-lobe consolidation,but very often a somewhat later stage ofthe disease finds it obliterated, whetherby extension of the consolidation to thisremote portion of the lung, or by oblitera-tion from a small collection of protectivefluid, makes little difference in the diflicultyof diagnosis.
