Pleural plaques are patchy collections of hyalinized collagen in the parietal pleura. [2] They have a holly leaf appearance on X-ray. [1] They are indicators of asbestos exposure, and the most common asbestos-induced lesion. [3]
These imaging techniques can detect fibrothorax and pleural thickening that surround the lungs. [7] The presence of a thickened peel with or without calcification are common features of fibrothorax when imaged. [3] CT scans can more readily differentiate whether pleural thickening is due to extra fat deposition or true pleural thickening than X ...
Pleural Abnormalities: Pleural abnormalities are reported with respect to type (pleural plaques or diffuse pleural thickening), location (chest wall, diaphragm, or other), presence of calcification , width (only of in profile pleural thickening seen along the chest wall edge), and extent (combined distance for involved chest wall).
In contrast a large pleural effusion, or the presence of a significant amount of fluid in the pleural space, may be a sign of active TB at any age. Solitary calcified nodules or granuloma - Discrete calcified nodule or granuloma, or calcified lymph node. The calcified nodule can be within the lung, hila, or mediastinum.
Conversely, 10 to 20% of patients with lung cancer are diagnosed in this way. [4] If the patient has a history of smoking or the nodule is growing, the possibility of cancer may need to be excluded through further radiological studies and interventions, possibly including surgical resection. The prognosis depends on the underlying condition.
Lung cancer, mesothelioma, pleural fibrosis, pulmonary heart disease [1] [2] Usual onset ~10-40 years after long-term exposure [3] Causes: Asbestos [4] Diagnostic method: History of exposure, medical imaging [4] Prevention: Eliminating exposure [4] Treatment: Supportive care, stopping smoking, oxygen therapy, [5] [4] lung replacement: Prognosis

Fluid in space between the lung and the chest wall is termed a pleural effusion. There needs to be at least 75 mL of pleural fluid in order to blunt the costophrenic angle on the lateral chest radiograph and 200 mL of pleural fluid in order to blunt the costophrenic angle on the posteroanterior chest radiograph. On a lateral decubitus, amounts ...
