 Discussion of Thymolipoma
- Thymolipoma is a rare, benign, slow-growing tumor that accounts for 2%–9% of all thymic neoplasms.
- Occurs most frequently in young adults
- Has no sex predilection.
- Thymolipoma is usually asymptomatic and manifests as a large anterior mediastinal mass.
- Histology: Composed of mature fat and thymic tissue.
- It is usually detected incidentally at routine chest radiography and may occasionally mimic cardiomegaly or an elevated hemidiaphragm
- Because of its soft and pliable nature, thymolipoma typically drapes itself around the heart and adjacent mediastinal structures, often becoming quite large before coming to clinical attention.
- Association with myasthenia gravis, Graves disease, aplastic anemia, and other hematologic disorders has been reported.
 Imaging Findings for Thymolipoma
- At CT and MR imaging, thymolipoma manifests as a fatty mass with fibrous septa.
