Calcified pleural plaques from asbestos exposure.

Civil rights law firms nyc. If the patient is upright when the x ray is taken then fluid will surround the lung base forming a meniscus a concave line obscuring the costophrenic angle and part or all of the hemidiaphragm. Asbestosis is fibrosis of the lung caused by the presence of asbestos fibres in the lungs themselves it may have similar appearances to the fibrosis seen on the previous page. Pleural plaques are a benign entity do not lead to cancer or mesothelioma and their presence does not equate to the diagnosis of asbestosis note.

Fluid gathers in the lowest part of the chest according to the patients position. Pleural plaques are typically identified through imaging scans. 2 case question available from the case.

The plaque appears in profile as a sharply marginated dense band of soft tissue ranging from 1 to 10 mm in thickness paralleling the inner margin of the lateral thoracic wall. The inner margin is often well defined because it is tangential to the x ray beam and the adjacent lung is a good contrast medium. Typically with sparing of the costophrenic angles.
