Abstract

Because of the controversy regarding the benefits of the lateral neck and chest radiographs in the evaluation of croup and epiglottitis, a two-part retrospective study was initiated. Part I consisted of a retrospective chart review of 44 patients with a final diagnosis of croup and epiglottitis. Part II consisted of the 42 lateral neck and chest x-rays from patients in part I presented to six radiologists who knew only the patients age and the history of respiratory distress. Two hundred forty-six responses were obtained. The results of the part I study showed that 64% of patients with documented epiglottitis had a positive radiologic diagnosis. Only 33% of patients with croup had a positive radiologic diagnosis and importantly 27% had a diagnosis of possible epiglottitis. The results of part II showed 38% of the documented epiglottitis patients had a positive lateral neck radiograph. The croup patients had a lateral neck and/or chest x-ray positive in 38%. Of interest, 24% had readings consistent with possible epiglottitis. Based on this two-part study, it is our conclusion that the lateral neck and chest x-ray may be unreliable and inaccurate in the diagnosis of croup and epiglottitis. Caution and good clinical judgement should be utilized when interpreting these x-rays.
