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]
The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the fourth and fifth intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode tracing as pleura and lung being indistinguishable as linear hyperechogenic lines and is fairly reliable for diagnosis of a pneumothorax.
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.
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.
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 ...
Ultrasonography uses sound waves to create an image. It may show where fluid is located in the chest. It also can show some tumors. Although ultrasound may detect fluid around the lungs, also known as a pleural effusion, sound waves are scattered by air. Therefore, an actual picture of the lungs cannot be obtained with ultrasonography.
Pleural empyema; Other names: Pyothorax, purulent pleuritis, lung empyema: CT chest showing large right sided hydro-pneumothorax from pleural empyema.

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.
