As he was recovering from the pneumonia he developed left-sided pleuritic pain and pleural effusion. At thoracocentesis an exudative pleural effusion contained 16% eosinophils with a simultaneous 28% peripheral eosinophilia. An allergic reaction to penicllins was thought to be the cause. After withdrawal of those medications and institution of pred-nisolone a rapid resolution was seen of symptoms, signs, peripheral eosinophilia and radiological abnormalities.", }
