CALCIFIED PLEURAL PLATES: HOLLYWOOD SIGN!
Asbestos, also known as asbestos, is a mineral fiber of silicate chains and is found in nature, presenting itself in two basic forms: chrysotile and amphiboles. Due to the high risk it poses to health, asbestos is becoming less used in the industry.
Exposure and inhalation to asbestos may result in various lung changes, being essentially occupational. It comes from various work contexts, such as contact and manipulation of textile products such as blankets and fabrics.
The alterations caused are not specific and the most frequent ones are benign, such as pulmonary fibrosis (asbestosis), visceral pleura (diffuse pleural thickening) or parietal pleura (pleural plaques). The presence of pleural plaques, especially if bilateral and calcified, is quite specific and pathognomonic
exposure to asbestos.
The x-ray examination refers to the formation of these bilateral pleural plaques. They are the most common manifestation and usually found after 20-30 years of exposure. They are often multiple, varying in size and extent, and calcified in 10% – 15% of cases. They tend to spread through the posterolateral, mediastinal and diaphragmatic faces and save the apex and costophrenic angles (as in the examination). In most cases they are identified accidentally and there is no specific therapy.
