Abstract
Intrathoracic benign neoplasm can develop from any tissue; inside the thoracic cavity, however, pleural lipomatosis is unusual diposition of adipose tissue in the pleural and subpleural layer. Asymptomatic presentation may be proven commonly and revealed by unintended radiology with a measured Hounsfield scale “100 to -50. We report this case of pleural lipomatosis by radiological finding
though thoracoscopic finding is the ideal for diagnosis and with. pathological examination of the specimen confirmed the diagnosis of lipomatosis. A radiological diagnosis of pleural lipomatosis can be made by computed tomography, transthoracic ultrasound as a diagnostic investigation because of their characteristic fat attenuation. Medical thoracoscopic biopsy provides a more
accurate and confirmed diagnosis. Pleural lipomatosis is a rare clinical pleural dilemma that needs suspicious sense and a feasible radiological diagnosis as soon as a strong evidence of malignant transformation is excluded. Excessive unencapsulated infiltrative fat deposition is known as mediastinal lipomatosis (Fig 5). Lipomatosis is commonly associated with obesity and exogenous steroid administration.
