Coal Worker's Lungs - Chest X-Ray

This chest X-ray shows coal worker's lungs. There are diffuse, small, light areas on both sides (1 to 3 mm) in all parts of the lungs. Diseases that may result in an X-ray like this include: simple coal workers pneumoconiosis (CWP) - stage I, simple silicosis, miliary tuberculosis, histiocytosis X (eosinophilic granuloma), and other diffuse infiltrate pulmonary diseases.

Coal Workers Pneumoconiosis - Stage II

This chest X-ray shows coal workers pneumoconiosis - stage II. There are diffuse, small (2 to 4 mm) light areas on both sides of the lungs. Diseases which may explain these X-ray findings include simple coal workers pneumoconiosis (CWP) - stage II, simple silicosis, disseminated tuberculosis, metastatic lung cancer, and other diffuse infiltrative pulmonary diseases.

Coal Workers Pneumoconiosis - Stage II #2

This chest X-ray shows coal workers pneumoconiosis - stage II. There are diffuse, small (2 to 4 mm each), light areas throughout both lungs. In the right upper lung (seen on the left side of the picture), there is a light area (measuring approximately 2 cm by 4 cm) with poorly defined borders, representing coalescence (merging together) of previously distinct light areas. Diseases which may explain these X-ray findings include simple coal workers pneumoconiosis (CWP) - stage II, silico-tuberculosis, disseminated tuberculosis, metastatic lung cancer, and other diffuse infiltrative pulmonary diseases.

Coal Workers Pneumoconiosis, Complicated #2

This picture shows complicated coal workers pneumoconiosis. There are diffuse, massive light areas that run together in the upper and middle parts of both lungs. These are superimposed on a background of small and poorly distinguishable light areas that are diffuse and located in both lungs. Diseases which may explain these X-ray findings include, but are not limited to: complicated coal workers pneumoconiosis (CWP), silico-tuberculosis, and metastatic lung cancer.

Respiratory System

Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.
