Key Points

• To explore the characteristics and diagnostic considerations of extramedullary hematopoiesis in the anterior mediastinum.
• Case analysis of anterior mediastinal extramedullary hematopoiesis with a focus on growth patterns and imaging characteristics.
• Discussion on the risks of biopsy for hypervascular lesions.
• Extramedullary hematopoiesis can mimic thymic tumors due to its slow growth rate and changing fat content.
• Histologic confirmation is crucial for accurate diagnosis and appropriate management.
