Abstrakt:	Background: Full-term infants with severe and prolonged respiratory distress represent a diagnostic challenge. Plain radiographic findings may be nonspecific or similar to classic surfactant deficiency disease for infants with surfactant protein B deficiency and acinar dysplasia.Objectives: To describe the similar clinical-radiolgical patterns of two rare neonatal conditions.Materials and Methods: Six newborn babies with severe respiratory distress at birth demonstrated clinical and radiographically prolonged and progressive diffuse pulmonary opacification.Results: All infants demonstrated hyperinflation of the lungs. The diffuse hazy opacification, which varied from mild (n=3) to moderate (n=3), progressed to severe diffuse opacification preceding death, which occurred at 12-36 days of life. Open lung biopsy confirmed the diagnosis of primary alveolar acinar dysplasia (AD) in four infants and surfactant protein B deficiency (SPBD) in two infants.Conclusions: In full-term babies with unexplained progressive respiratory distress from birth and progress of radiological changes, both AD and SPBD should be considered.
