Spontaneous mediastinal hemorrhage: a case report with a review of the literature.

A patient on chronic hemodialysis presenting with shortness of breath and dysphagia was found to have massive hemomediastinum. A review of the world's literature prompted by this case reveals that this rare entity can be classified into three general groups: (1) hemomediastinum secondary to underlying bleeding disorder, (2) hemomediastinum secondary to hemorrhage into a mediastinal organ or gland, without underlying bleeding disorder and (3) idiopathic hemomediastinum, without underlying bleeding disorder. Therapy depends upon the underlying etiology and the severity of symptoms.
