Acute pleurisy presenting as a post myocardial infarction syndrome.

We report a case of Dressler's syndrome in which the diagnosis was made fol lowing an investigation of pleurisy which the laboratory data revealed as i nflammatory. A myocardial infarction which had occurred two months earlier had passed unnoticed. The principal value of this case was to draw attentio n to the syndrome which may initially be a pleurisy but also clinically the picture may mimic pneumonia, both alone or together may be associated with classical pericarditis. Pleurisy occurs in Dressler's syndrome but it is r arely the presenting diagnosis as the cardiac picture tends to predominate.
