Pneumothorax vs. Emphysema — What's the Difference?

A pneumothorax is an abnormal collection of air in the pleural space between the lung and the chest wall. Symptoms typically include sudden onset of sharp, one-sided chest pain and shortness of breath.

A pathological condition of the lungs marked by an abnormal increase in the size of the air spaces, resulting in labored breathing and an increased susceptibility to infection. It can be caused by irreversible expansion of the alveoli or by the destruction of alveolar walls.

Accumulation of air or gas in the pleural cavity, occurring as a result of disease or injury, or sometimes induced to collapse the lung in the treatment of tuberculosis and other lung diseases.

An abnormal distension of body tissues caused by retention of air.

(medicine) Presence of air inside the pleural cavity, usually caused by injury either to the lung or the chest wall.

(pathology) An abnormal accumulation of air or other gas in tissues, most commonly the lungs.

A condition in which air or other gas is present in the cavity of the chest; - called also pneumatothorax.

(medicine) Pulmonary emphysema, a chronic lung disease, one type of chronic obstructive pulmonary disease.

Abnormal presence of air in the pleural cavity resulting in the collapse of the lung; may be spontaneous (due to injury to the chest) or induced (as a treatment for tuberculosis)

A swelling produced by gas or air diffused in the cellular tissue.

An abnormal condition of the lungs marked by decreased respiratory function; associated with smoking or chronic bronchitis or old age
