There are some calcified and non calcified pleural plaques associated with right sided plural thickening , bilateral pleural effiution and adjacent round atelectasis .
Asbestosis related lung and plural disease
Discussion (Related Text)
Asbestosis typically occurs 10 - 15 years following the commencement of exposure to asbestos and is dose related .Clinical presentation is insidious and non-specific with shortness of breath prompting imaging. Alternatively, the presence of asbestosis may become evident when a patient presents with other asbestos related diseases.Asbestosis is histologically very similar to usual interstitial pneumonia (UIP) with the addition of asbestos bodies . iThere are no pathognomonic radiological features specific for asbestosis.Plain films may show may irregular opacities with a fine reticular pattern. Additional evidence of asbestos exposure such as calcified or non-calcified pleural plaques may be evident. Appearances of asbestosis vary with the duration and severity of the condition. Early manifestations are largely confined to the peripheral region of the lower zones and are subtle. They include: centrilobular dot-like opacities : peribronchiolar fibrosis intralobular linear opacities : reticulation sub pleural lines (often curvilinear) These changes may be similar in appearance to dependent atelectasis, especially when located posteriorly, and thus supine and prone scans are recommended . As the fibrosis progresses, a number of more definite findings are seen, which continue to be particularly subpleural and lower lung zone in distribution. They include: parenchymal bands traction bronchiectasis honeycomb fibrosis Pleural effusions and pleural plaques are common manifestations of asbestos related disease, however hilar and mediastinal lymphadenopathy is usually absent. A careful search for malignancy both of the lung (bronchogenic carcinoma) and pleura (mesothelioma) should be undertaken especially in nodal enlargement is seen.
