A 30 year-old woman, who had been an out-patient of neurology department because of anorexia nervosa for 13 years, consulted at our department complaining of neck and throat pain, lasting for 3 days, induced by strain. Neck swelling was unclear on inspection but palpation revealed subcutaneous emphysema in the whole neck region. Mediastinal emphysema was also observed on plain X-ray film and CT scan. Both emphysemas were thought to be caused by increasing air-way pressure due to strain and loss of elasticity of the alveolar tissue, which was believed to be caused by the low nutritional state of the patient's anorexia nervosa. She was treated with rest and prophylactic antibiotics. Though the emphysemas subsided uneventfully, liver dysfunction due to the anorexia nervosa progressed. The patient was transferred to the internal medicine ward to treat this dysfunction after the emphysemas had disappeared.
