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]
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 ...
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 ...
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.
A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by cancer. While this procedure usually generates only limited scar tissue, in rare cases a fibrothorax can develop.
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.
A parapneumonic effusion is a type of pleural effusion (accumulation of fluid in the pleural cavity) that arises as a result of a pneumonia, lung abscess, or bronchiectasis. [1] There are three types of parapneumonic effusions: uncomplicated effusions, complicated effusions, and empyema. Uncomplicated effusions generally respond well to ...
