Imaging findings in eating disorders

Abstract

Objective: Eating disorders, such as anorexia nervosa and bulimia nervosa, are often undiagnosed but potentially treatable illnesses that, if not identified, can lead to morbidity and death. Often, because of embarrassment or social stigma, patients do not readily admit to these disorders when interviewed by caregivers. Imaging findings can suggest the presence of an eating disorder; understanding these findings allows the radiologist to contribute to the diagnosis of these insidious conditions and alert the referring caregiver. Current concepts in eating disorders and their multimodality imaging findings in several organ systems will be reviewed.

Conclusion: After reviewing this article, the radiologist will understand the imaging findings in eating disorders. This knowledge will empower the radiologist to raise the question of a patient's eating disorder, a condition that may be unsuspected by the referring caregiver and could otherwise remain undiagnosed.
