Lipomas are benign mesenchymal tumors originating from fat tissue. Mediastinal lipomas are very rare, constitute 1.6% - 2.3% of all primary mediastinal tumors and most commonly located at anterior mediastinum. It is often asymptomatic and is detected incidentally on radiographs taken. The symptoms that it creates caused by the pressure it has on the surrounding organs. If it is asymptomatic, follow-up is sufficient, but complete excision is needed for the symptomatic cases.
