  1. Thymolipoma
    1. Recognize the typical radiologic appearance of thymolipoma, as well as its radiologic mimics
    2. Recognize the expected FNA findings, as well as other fat containing lesions which may occur in this location

    2. Recognize the more aggressive clinical behavior of mediastinal SFT, as compared with other sites
    3. Become familiar with expected FNA findings of this tumor and the utility of immunohistochemical stains to confirm the diagnosis, provided an adequate cell block preparation is available
  3. Liposarcoma
    1. Recognize liposarcoma as the most common malignant mesenchymal tumor of the mediastinum
