[A case of idiopathic mediastinal fibrosis with fatal outcome]

Particular difficulties arise when trying to classify mediastinal fibrosis and determining its etiology and clinical evolution. In this paper, the Authors describe a case of mediastinal fibrosis which was characterized by a specific clinical origins (mild fever-anemia). It was not possible to establish the real etiology of the mediastinal lesion which in the end led to an unfavourable outcome that was linked to the local development of the illness, in spite of its benign histological characteristics.
