Abstract
A 15-year-old junior highschool girl who developed anorexia nervosa with pneumomediastinum, pneumoretroperitoneum and subcutaneous emphysema.At her first visit to hospital, her body weight was 34.5kg(BMI 13), and 7 days later reduced to 29.5kg(BMI 11.1). At that time, radiographical examination demonstrated air in the mediastinal, retroperitoneal and subcutaneous space. Blood coagulation test showed pre disseminated intravascular coagulation. She was immediately hospitalized.Rested in bed and infused gabexate mesilate, her blood coagulation test normalized 1 week after, soft tissue emphysema diminished 3 weeks after.Soft tissue emphysema is considered to occur by weakness of soft tissue from malnutrition.So, when weight was lost within a short time, we have to pay careful attention to the anorectic patient, because severe complications are suspected to occur.
