The baby’s chest x-ray shows increased texture in both lungs, which should be indicative of bronchiectasis. First of all, it is important to understand the concept of lung texture, which refers to the projection of the trachea of the lung and also includes a part of the blood vessels on the chest X-ray. Pulmonary texture normally should not suggest more than the outer 1/3 of the lung on the chest X-ray, and it is not visible from the outer 1/3 of the lung. If the doctor suggests on the imaging report that there is increased lung texture, it must be more than the outer 1/3 of the lung. This is mostly due to tracheomalacia, but it may also be a pulmonary vascular disease, and of course there are vascular problems in addition to trachea, or it may be congenital heart disease, etc. The patient should be given further examination, such as heart check, ultrasound check, in addition to sputum, infection problems, and give appropriate treatment.
