CTICasesExtramedullary Hematopoiesis
Imaging findings
Multiple posterior mediastinal masses with fat density intermixed with soft tissue. Associated marked abnormalities in the osseous structures, specifically the ribs and clavicles, in a young patient.
Key takeaways
In patients with conditions like beta thalassemia, compensatory extramedullary hematopoiesis can present as bilateral posterior mediastinal masses. The presence of fat density is a characteristic feature of this marrow-derived process.
