|Title||Pleural Based Lipoma|
|Text||Pleural based lipomas are thought to arise from subpleural adipose tissue. This masses are rarely symptomatic. They can cause focal swelling and are sometimes palpable.
Pleural lipomas present on plain film as smoothly contoured, convex masses arising from the pleural surface. On CT, uniform fat attenuation (-70 to -120 HU) confirms the diagnosis.
Concern for liposarcoma is raised when the mass is heterogenous showing a mixture of fat and soft tissue attenuation. Pleural based liposarcoma is rare.
