A 55-year-old patient presented with an anterior mediastinal mass initially concerning for neoplasm. Follow-up CT scans demonstrated complete involution of the mass, confirming a benign, mass-like thymus.
Key takeaways
In middle-aged or older patients, an anterior mediastinal mass that appears well-circumscribed and contains mixed fat/soft tissue should prompt consideration for transient thymic hyperplasia before aggressive intervention.
