Quizplus · Accepted Answer

The characteristic chest radiograph shortly after birth shows diffuse streakiness and fluid in the major and minor fissures. This is impossible to distinguish from the chest radiograph of pneumonia. The characteristic of TTNB results from rapid resolution of the disease. By 24 hours of age, the newborn's chest radiograph is typically normal.
