We retrospectively analyzed the clinical and radiologic findings of broncho-pulmonary dysplasia.

We retrospectively studied the chest radiographs of 10 infants, who were clinically diagnosed as bronchopulmonary dysplasia from January, 1994 to December, 1995.

The underlying disease of the cases that has BPD were, there were hyaline membrane disease in 4 cases, repeating apnea in 4 cases, septicemia, peneumonia in 2 cases.

The most common radiological findings were coarse nodular & streaky densities in perihilar region(7/10),emphysematous overdistention(6/10), and other findings such as bubbly pattern (3/10), lace-like pattern with strands of density(2/10) appeared.

Premature and infants with thigh oxygen and intermittent positive pressure ventilation therapy, the chronic persistent pulmonary abnormality in chest X-ray films highly suggests the possibility of bronchopulmonar dysplasia.
