Storch et al (1981; 245:587), evaluating the chest roentgenograms in sporadic cases of Legionnaires' disease diagnosed by serological findings, commented that the roentgenograms would be indistinguishable from those showing pneumococcal pneumonia. They obtained only 18 of 100 sets of roentgenograms they sought, explaining that the patients whose physicians sent them (18) may have been different from those whose physicians did not.
