Increased texture in both lungs in infants is a term commonly used by radiologists to report chest radiographs when clinicians choose to take chest radiographs of infants. Increased texture in both lungs may be a sign that the child has a respiratory infectious disease. If increased texture in both lungs is evident, accompanied by symptoms such as cough, sputum and fever, and sputum sounds are heard on lung auscultation, bronchitis may be present. If the child has pulmonary edema and pulmonary congestion, the child may also show increased texture in both lungs. If the child has no clinical symptoms and simply shows increased lung texture, it may be normal, so it should be analyzed in the context of the child’s specific situation.
