Panfine bronchiolitis, i.e., diffuse panfine bronchiolitis, is characterized on imaging by increased lung field translucency seen on chest CT, with a diffuse distribution of small nodular shadows centered on the lung lobules.
It is a chronic inflammatory disease of the airways, and the site of involvement is usually the distal terminal airways of the respiratory fine bronchi of both lungs. Clinical manifestations are coughing up sputum and shortness of breath, which may lead to dyspnea in severe cases.
Clinically, the disease is usually diagnosed by X-ray, CT, and high-resolution CT imaging, and is usually characterized by increased lung field translucency, diffuse distribution of nodular shadows in the center of the lung lobules, predominantly in the two lower lobes and the outer bands of the lungs, with fuzzy margins, absence of thickening of the interlobular septa, and thickening of the bronchial walls. For atypical clinical and imaging changes, lung tissue biopsy is required.
Patients with panfine bronchitis are advised to go to regular hospitals for diagnosis and treatment under the guidance of doctors to avoid the abuse and generalization of drugs.
