Abstract

Localized interlobar pleural effusion appearing during the course of congestive heart failure was first reported by Stewart in 1928.1 A second report by Kiser2 appeared shortly after, and since then cases have been noted in the literature with increasing frequency.

Such effusions are characterized by their reversibility. They appear during congestive heart failure and clear rapidly when the failure responds to treatment or disappears spontaneously. Having once appeared as a feature of heart failure, interlobar effusions tend to recur with subsequent episodes.3

The radiographic picture is variable and depends on the location and amount of the fluid. It is most commonly seen between the upper and middle lobes of the right lung, but occasionally may appear on the left side.4 The roentgenographic appearance is generally that of an ovoid or elliptical shadow,4a but associated abnormalities of the lung or hilum can distort the symmetry of
