Spontaneous pneumothorax Spontaneous pneumothorax is by far the commonest form in clinical practice and is always secondary to pulmonary or pleural abnormality. This may be congenital or due to acute or chronic acquired disease. Classification 1.Primary spontaneous (idiopathic)pneumothorax which occurs in healthy persons 2.Secondary spontaneous pneumothorax which occurs in persons with diseases that affect the lung

Aetiology 1.Primary spontaneous pneumothorax (idiopathic) Defined as a pneumothorax occurring in patients without obvious pulmonary disease clinically or on chest X-ray, although chest CT usually reveals subapical blebs and bullae. 2.Secondary spontaneous pneumothorax Defined as a pneumothorax occurring in patients with underlying lung disease

Clinical types 1.Closed pneumothorax There is no movement of air takes place because the hole through which air entered has been sealed off
