On radiological studies, a pleural pseudotumor is visualized as a biconcave or lenticular lesion using conventional chest x-rays and CT scans. The lesion is most commonly located in the minor (horizontal) fissure of the lung. A pleural pseudotumor is also associated with the presence of dependent pleural effusions. [9]
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] They usually appear after 20 years or more of exposure and never degenerate into mesothelioma.
A Chest radiograph is usually performed first and may demonstrate an underlying lung cancer as well as the pleural effusion. Ultrasound has a sensitivity of 73% and specificity of 100% at distinguishing malignant pleural effusions from other causes of pleural effusion, based on the presence of visible pleural metastases, pleural thickening ...
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
eFAST (extended focused assessment with sonography for trauma) allows an emergency physician or a surgeon the ability to determine whether a patient has pneumothorax, hemothorax, pleural effusion, mass/tumor, or a lodged foreign body. The exam allows for visualization of the echogenic tissue, ribs, and lung tissue.
Over the years pleural SFTs acquired a number of synonyms, including localized fibrous tumor, benign mesothelioma, localized fibrous mesothelioma, submesothelial fibroma, and pleural fibroma. The use of names that include mesothelioma for this tumor is discouraged because of potential confusion with diffuse malignant mesothelioma , a much more ...
Pleural tumors may be benign (i.e. solitary fibrous tumor) or malignant in nature. Pleural mesothelioma is a type of malignant cancer associated with asbestos exposure. Under most other circumstances, pleural cancers are secondary malignancies associated with lung cancer due to its nearby location or as metastasis such as with breast cancer.
Diagnosis can be via CXR. CT is better for outlining borders of air-fluid levels, however, CT has a greater radiation exposure.. Ultrasound imaging has also proven to be a useful tool for hydropneumothorax diagnoses by looking for the absence of the characteristic "curtain sign" usually seen in ultrasound images at the base of healthy lungs.
