CTICasesGiant Mediastinal Lipoma
Imaging findings
CT chest shows a giant, fat-attenuating mass in the anterior mediastinum, extending from the neck to the diaphragm, wrapping around the major mediastinal vessels with minimal mass effect.
Key takeaways
Giant lipomas of the mediastinum are rare, benign, slow-growing tumors. Because they consist of soft, fatty tissue, they can grow to massive sizes and infiltrate multiple compartments without compressing major vascular structures. Differentiation from low-grade liposarcoma can be challenging.
