Imaging findings
The anterior left chest mass appeared largely fatty on CT attenuation, with prominent internal vessels and areas of higher attenuation soft-tissue nodularity. Biopsy confirmed the mass as a hibernoma, a rare tumor arising from brown fat.
Key takeaways
When evaluating an anterior chest mass that appears predominantly fatty but contains internal enhancing soft tissue, consider a hibernoma. These can arise in various soft tissue locations and may mimic other tumors.
