Pleural plaques (PP) are considered to be hallmarks of asbestos exposure. They constitute focal thickenings of the pleura and are commonly seen in patients without lung disease. They can involve parietal, diaphragmatic and mediastinal pleura. Chest x-ray is frequently used for PP diagnosis, but computed tomography, especially when used the high-resolution technique, is the imaging exam with the greatest sensibility and specificity. PP are almost always asymptomatic, but there are some controversial about their relationship with asbestos exposure indexes, pulmonary functional alterations and risk of neoplasias.
胸膜斑被认为是石棉暴露的标志。它们构成胸膜的局灶性增厚，常见于无肺部疾病的患者。可累及壁层、膈胸膜和纵隔胸膜。胸部X线常用于胸膜斑的诊断，但计算机断层扫描，尤其是采用高分辨率技术时，是敏感性和特异性最高的影像学检查。胸膜斑几乎总是无症状的，但关于它们与石棉暴露指数、肺功能改变及肿瘤风险之间的关系存在一些争议。
