Recurrent subcutaneous emphysema as a consequence of bulimia nervosa
International Journal of Eating Disorders, 08/20/2012
McCurdy JM et al. – Recurrent subcutaneous emphysema is probably secondary to recurrent pneumomediastinum in a woman with bulimia nervosa. It is believed that increased intrathoracic pressure and nutritional deficiency associated with repeated induced vomiting contributed to this complication. This is the only case of recurrent subcutaneous emphysema. While in this case, and in most cases, the course was benign with eventual reabsorption of the subcutaneous air, pneumomediastinum can be a life–threatening complication of bulimia nervosa.
