What is the cause of increased bilateral lung texture?

The increase in bilateral lung markings cannot be ignored, as some may be pathological, some may be physiological or technical problems, so they must be treated differently. The increase in vascular lung markings may be caused by diseases such as dementia or rheumatic heart disease.

1. Reasons

There are many reasons for increased lung markings, which can be pathological, physiological or technical. Generally speaking, isolated reports of increased lung markings are of little clinical value. Only by carefully analyzing the nature of the increased lung markings and considering them in combination with other X-ray manifestations, clinical conditions and technical conditions can the correct conclusion be drawn. Regardless of the cause of the increased lung texture, good health diagnosis and treatment and rehabilitation therapy are required.

2. Classification

1. Increased vascular lung markings: The lung markings are coarse, and the blood vessels are maintained from the hilum to the lungs, often accompanied by an enlarged heart, which is mainly seen in rheumatic heart disease, congenital heart disease, etc.

2. Increased lymphatic lung markings: The lung markings appear as fine reticular patterns in both lungs, which are commonly seen in pneumoconiosis, carcinomatous lymphangitis, etc.

3. Increased lung markings due to smoking: Increased lung markings on both lungs, but normal movement, mainly due to carbon monoxide deposition caused by long-term smoking.

4. Physiological increase in lung markings: mainly seen in the elderly and obese people. The former is due to the fact that the lung interstitium of the elderly is relatively abundant, which makes it more obvious on chest X-rays.

The latter is due to the obese physique of the examinee and the increase of subcutaneous fat, which leads to increased X-ray absorption, thus causing the illusion of increased lung texture on the chest X-ray.

5. Increased bronchial lung markings: The lung markings are uneven in thickness, often mixed with deformed markings and small honeycomb shadows, which are common in chronic bronchitis, bronchiectasis, etc.
