Mediastinal fibrosis. A case report.

Mediastinal fibrosis may be part of a multifocal fibrotic disease, including retroperitoneal fibrosis, lung fibrosis and Riedel's struma. A case of mediastinal fibrosis, with a previous history of retroperitoneal fibrosis and lung fibrosis, is discussed. There are many known causes of retroperitoneal and mediastinal fibrosis, but as in the present case the etiology often remains unknown.
