[Asymptomatic mediastinal and neck emphysema after Kussmaul's respiration and purging].

This is a case report of a young woman with diabetes mellitus type 1. She was admitted with severe diabetic ketoacidosis. Asymptomatic "surgical emphysema", pneumomediastinum and bilateral pneumothoraces were accidently discovered. The emphysema had probably occurred due to laboured breathing and groaning during her diabetic ketoacidosis. No treatment was needed.
