After reviewing this exhibit, the learner will be able to: 1. Realize that enhancing fat containing soft tissue tumors are not always liposarcomas. 2. List differential diagnoses of benign enhancing fat containing soft tissue tumors on MR imaging. 3. Describe their clinical and MR imaging findings. 

I. Background    1. Liposarcomas are malignant soft tissue tumors which often contain fat component and can have some portions of enhancement.    2. Benign lipomas usually does not have enhanced component. However, some benign fat containing soft tissue tumors can be enhanced on MR imaging, which can have the similar appearances with liposarcoma.   II. Benign fat containing soft tissue tumors with contrast enhancement.    1. spindle cell lipoma    2. angiolipoma    3. lipoblastoma    4. hibernoma    5. hemangioma    6. heterotopic osssfication
