What is pleural based mass?
Pleural tumors are found in the pleural space—the cavity between the lungs and chest wall that contains lubricating pleural fluid. A pleural tumor is almost always metastatic (cancerous) and difficult to operate on. The prognosis is seldom encouraging.
What is pleural fat?
Pleural lipomas are the most common benign soft tissue tumor of the pleura. These lesions are thought to originate from the submesothelial layers of the parietal pleura, extending into the subpleural, pleural, or extrapleural space. Pleural lipomas are encapsulated fatty tumors with a slow growth rate.
Can a pleural based nodule be benign?
Most of these tumors are benign, but in 20% cases, they can be malignant. The tumor usually arises from the visceral pleura in 80% of cases.
Is pleural thickening serious?
Is Pleural Thickening Serious? Pleural thickening can be serious, especially when it reaches more advanced stages. The presence of pleural thickening is not enough to confirm a pleural mesothelioma diagnosis, but it can be a sign of serious and significant asbestos exposure.
How long can you live with pleural thickening?
Symptoms may include chest pain, chronic cough, and shortness of breath. The average life expectancy for pleural mesothelioma after diagnosis is about 1-2 years, but specialized life-extending treatments are available.
Can lipomas grow in the lungs?
Lipoma. Although lipomas are the most common benign neoplasms in humans, lung parenchymal involvement is rare. They are well-circumscribed mesenchymal tumors that originate from adipose tissue. The most common parenchymal location is in the periphery surrounded by normal lung tissue (,4).
What is a lung hamartoma?
Hamartoma is a clinically frequent benign lung tumor, accounting for 77% of all benign lung tumors [3]. As for the radiographic characteristics, they are typically smooth, well-circumscribed nodules, round or oval, with heterogeneous internal structures. Popcorn-like calcification may also be observed.
How do you get rid of pleural thickening?
In most cases, no treatment is needed since the pleural thickening does not usually cause very severe symptoms. Stopping smoking, keeping active and pulmonary rehabilitation (PR) are usually the most helpful options. If your breathlessness is severe, surgery can very occasionally be considered.
How are pleural neoplasms related to extrapleural fat?
Extrapleural neoplasms may arise from extrapleural fat, ribs, intercostal muscles, and neurovascular bundle; typical pleural neoplasms do not cause erosion of ribs and displace the extrapleural fat outward, while extrapleural neoplasms displace the extrapleural fat inward [Table 1].

Is there fat outside the parietal pleura?
However, fat-containing lesions of the chest (e.g. hamartoma) should also be considered. Extrapleural fat represents fat outside the parietal pleura. It is part of the loose connective tissue of the endothoracic fascia, most abundant along the posterolateral aspects of the 4 th through 8 th ribs.
Which is the most common soft tissue tumour of the pleura?
Pleural lipoma. Pleural lipomas are the most common benign soft tissue tumour of the pleura. These lesions are thought to originate from the submesothelial layers of the parietal pleura, extending into the subpleural, pleural, or extrapleural space. Pleural lipomas are encapsulated fatty tumors with a slow growth rate.
Where is extrapleural fat located in the chest?
Extrapleural fat is fat outside the parietal pleura in the chest wall. It is a component of the loose connective tissue of the endothoracic fascia and is most abundant along the posterolateral aspects of the fourth through eighth ribs bilaterally ( ,43, ,44).
