Abstract The authors report a new method of diagnosing hyaline membrane disease (HMD) in newborns: ultrasound. Babies with HMD display a specific pattern with retrohepatic hyperechogenicity on abdominal ultrasound. The specificity of the pattern was verified in 40 prematures with respiratory distress syndrome. The sign was present in 24, and in 22 of these the final diagnosis was moderate or marked HMD. In the last 2, mild HMD was suggested. The pattern was absent in the 16 others, none of whom had HMD. The pattern probably results from an ultrasound artifact: summation of multiple aerated airways surrounded by collapsed alveoli. Follow-up examinations were possible in 13 babies with HMD. Hyperechogenicity disappeared in 8 of these patients within 6–9 days and in 3 within 10–20 days; it persisted for 60 and 70 days in 2 with bronchopulmonary dysplasia. In conclusion, retrohepatic hyperechogenicity in newborns is pathognomonic for HMD and allows an instant diagnosis. The persistence of the pattern could be a useful criterion for evaluation of the prognosis.
