thickening of lung markings

Introduction

Introduction Thickening of the lung texture: The lung texture refers to the radiation strip shadow that extends from the hilar to the periphery of the lung field as seen during chest imaging. It consists mainly of pulmonary artery, pulmonary vein, bronchus and lymphatic vessels containing a certain amount of surfactant, which makes the alveoli easy to expand after birth. The lung texture on the chest X-ray is increased.

Cause

Cause

The diseases that often cause this symptom include chronic bronchitis, bronchiectasis, rheumatic heart disease, congenital heart disease, pneumoconiosis, cancerous lymphangitis, and other respiratory and rhythm, lung rales, and pulmonary heart valve second heart sound hyperactivity. Chest radiographs showed patchy or wedge-shaped shadows in the lungs, diaphragmatic elevation of the discoid atelectasis, pulmonary artery thickening and localized lung texture reduced blood gas analysis PaO2<10, 64kpa, alveolar oxygen partial pressure and arterial oxygen partial pressure The difference was increased; the dead space/tidal volume ratio (VD/VT) was >40%; the blood lactate dehydrogenase was >450 U, and the aspartate aminotransferase (AST) and creatine phosphokinase (CPK) increased the normal hemoglobin.

(1) Increased bronchial lung texture: manifested as uneven thickness of the lung texture, which often contains deformation texture and small honeycomb shadow, which is common in chronic bronchitis and bronchiectasis.

(2) Increased vascular lung texture: The lung texture is coarse, and the characteristics of keeping the blood vessels from the hilar to the lung are often accompanied by the manifestation of cardiac enlargement, mainly in rheumatic heart disease and congenital heart disease.

(3) Increased lymphatic lung texture: The lung texture is slender in the lungs, which is common in pneumoconiosis and cancerous lymphangitis.

(4) Increased smoking lung texture: showed increased lung texture, but normal walking, mainly due to carbon deposition caused by long-term smoking.

(5) Increased physiological lung texture: mainly found in the elderly and obese. The former is due to the relatively abundant lung interstitium in the elderly, which shows an increase in lung texture on the chest X-ray; the latter is due to the obesity of the subject, increased subcutaneous fat, resulting in increased X-ray absorption, resulting in increased lung texture on the chest radiograph. The illusion of.

Diagnosis

Differential diagnosis

Clinically often identified with lobular pneumonia. Lobular pneumonia is a focal acute suppurative inflammation in the lobules of the lung. Because the lesion is mostly centered on the bronchioles, it is also called bronchial pneumonia. The lesion begins in the bronchi and spreads to the alveoli surrounding it. More common in children and the elderly and infirm. The main clinical manifestations are fever, cough, cough and other symptoms, auscultation of the lungs can be heard and scattered wet sound.
