mediastinitis

Inflammation of the mediastinum.

Acute mediastinitis
A fulminant infectious process with a high morbidity and mortality, in which organisms rapidly spread through areolar planes of mediastinum.
 
Aetiology
Traumatic oesophageal perforation, foreign bodies, suture line leakage, post-emetic rupture.
 
Clinical
Chest pain, dysphagia, respiratory distress, cervical-upper thoracic subcutaneous crepitus.
 
Imaging
By chest X-ray (CXR); may be normal early, followed by evidence of mediastinal and subcutaneous air.
 
Management
Aggressive and early with antibiotics; fluid resuscitation; chest tubes for pneumothorax or effusions; thoracotomy and surgical repair.
 
Chronic mediastinitis
A relatively indolent process characterised by chronic (“round cell”) inflammation and fibrosis.
 
Aetiology
Most often the result of a granulomatous process (e.g., TB, histoplasmosis) but may be idiopathic, as in sclerosing mediastinitis.
 
Clinical
Often silent if no oesophageal obstruction occurs.
 
Imaging
CXR; may be normal or mediastinum widened.
 
Management
Thoracotomy to confirm diagnosis or relieve obstruction.
