Abstract:
When significant weight loss occurs in anorexia nervosa, routine physical examination may reveal the striking phenomenon of myoedema or muscle mounding. This refers to the way in which a localised short-lasting swelling may be induced in a voluntary muscle as a result of tactile percussion, ideally with a patellar hammer. The present case report describes this finding in a patient with anorexia nervosa and discusses its physiological and clinical significance. It is suggested that as a clinical sign myoedema may be of value in the management of anorexia nervosa by challenging the denial of illness which is so characteristic of it.
