We report the case of a patient with anorexia nervosa accompanied by acute subdural haematoma following a fall. A 34-year-old Japanese woman had serious medical complications and brain atrophy. After careful nutritional treatment, her laboratory test results improved and brain atrophy was reversed, and we prevented to perform surgery. However, unexpected prominent oedema of her lower legs and pleural effusion occurred. After receiving treatment for these symptoms, she eventually returned to her former occupation and started following a normal diet. Very few cases of anorexia nervosa accompanied by intracranial haemorrhage have been reported. Coagulation disorder and brain atrophy are supposed to be the primary causes of haematoma formation in the present case. Intracranial haemorrhage likely occurs in patients with anorexia nervosa despite minor head trauma. Because anorexia nervosa is not rare and the age of such patients is advancing, knowledge regarding this disorder would be useful for neurosurgeons.
