J98.5: Diseases of mediastinum, not elsewhere classified

Diseases of the mediastinum not elsewhere classified refer to conditions affecting the mediastinum, an area located in the central region of the thorax (the chest). This area is situated between the lungs and contains several vital structures including the heart, major blood vessels, windpipe, and esophagus, among others. Diseases in this area may arise from abnormalities or disorders of these structures, or even from infection or malignancy spread from adjacent organs. Symptoms of mediastinal diseases can vary greatly depending on the specific condition and the structures it affects. Some common symptoms may include chest pain, cough, shortness of breath, and difficulty in swallowing. These diseases can often escalate progressively, causing significant discomfort and potentially serious complications if not diagnosed and managed in a timely manner. The precise cause, progression, and impact on the individual can vary significantly depending on the specific disease involved.
