Abstract
Introduction:
Spontaneous pneumomediastinum is a rare complication of dermatomyositis.
Case Report:
We report a case of pneumomediastinum with massive subcutaneous emphysema occurring in a female patient with dermatomyositis treated with cortico-steroids.
Conclusions:
Our case illustrates perfectly the mechanism of spread of air along the broncho-vascular structures and also explains the presence of pneumomediastinum in the absence of pneumothorax.
