title: Mediastinal hibernoma presenting with hoarseness.
abstract: Hibernoma is an unusual benign soft tissue tumor derived from a specialized form of brown fat. A case of a 52-year-old female who was admitted with a slowly worsening hoarseness is presented. Further investigation revealed a left upper mediastinal mass next to the aortic arch. Upon surgical exploration a soft encapsulated mass was identified. Pathology was consistent with hibernoma. Despite their benign behavior, some variants of hibernoma can be confused histologically with liposarcoma. Therefore, long-term follow-up is advisable.
