[A case of Marchiafava-Bignami disease caused by anorexia nervosa].

A 29-year-old female without alcoholism whose height and weight were 152 cm and 28 kg had complained of severe anorexia since about 10 years ago. The splenium of the corpus callosum showed symmetrically low-intensity area in T1 WI and high-intensity area in T2 WI on her brain MRI. These findings could be reversible by the recovery of her nutritional condition. The findings of neurological and neuropsychological examinations were normal. To our knowledge, this is the first case report of Marchiafava-Bignami disease caused by Anorexia Nervosa.
