Question
A child experiences shortness of breath and uneven breathing when running or talking. Besides these symptoms, it is unclear what is related: the child is now 5 and a half years old but has difficulty articulating words clearly. In October 2009, an X-ray taken in the hospital incidentally showed increased lung texture.
Answer
Increased lung texture is usually caused by one of the following reasons: (1) Urinary tract lung texture hyperplasia, commonly seen in chronic bronchitis and bronchiectasis. (2) Vascular lung texture hyperplasia, commonly seen in rheumatic heart disease and congenital heart disease. (3) Lymphatic lung texture hyperplasia, commonly seen in pneumoconiosis and cancerous lymphangitis. (4) Lung texture hyperplasia caused by smoking, commonly seen in long-term smokers. (5) Physiological lung texture hyperplasia, commonly seen in the elderly and obese. It is recommended to undergo a thorough examination again to confirm the specific situation and receive timely treatment.
