Description: Mediastinitis is an inflammation of the mediastinum, the central compartment of the thoracic cavity located between the lungs. This condition can be caused by various reasons, including infections, trauma, or postoperative complications, especially following thoracic surgeries. Mediastinitis may present with symptoms such as fever, chest pain, difficulty breathing, and general malaise. The inflammation can affect vital structures such as the heart, major blood vessels, and the esophagus, which can lead to serious complications if not properly treated. Diagnosis is made through imaging studies, such as X-rays or computed tomography, and laboratory analyses. Treatment typically involves the use of antibiotics and, in severe cases, may require surgical intervention to drain abscesses or remove infected tissue. Mediastinitis is a serious condition that requires immediate medical attention to prevent potentially life-threatening complications.
