Cervical manifestations of fibrosing mediastinitis: a diagnostic and therapeutic dilemma.
Fibroinflammatory and fibrosclerosing lesions involving the head and neck outside the thyroid and orbit are exceedingly rare.

These cases indicate that a subset of fibroinflammatory and fibrosclerosing lesions found in the head and neck originate in the mediastinum.
