Chest x-ray demonstrates a rounded mass projecting over the mediastinum. The descending aorta can clearly be seen through it suggesting the mass is anterior.

CT confirms that the mass is in the anterior mediastinum. It is well-circumscribed, with no evidence of invasion into mediastinal structures. It is composed of a mixture of fat, fluid and soft tissue density material.
Case Discussion
The presence of fat suggests that the main differential is between a mature mediastinal teratoma or a thymolipoma. Unfortunately, no followup is available.
