Answer

A chest radiograph may reveal rib fractures or pneumomediastinum in the presence of other examination and laboratory findings to suggest repetitive vomiting. Patients may also show evidence of osteopenia.

Radiographic evidence of emphysematous changes may be present on chest computed tomography (CT) scans of patients with anorexia nervosa [98] ; however, these changes resolve with refeeding and weight normalization, unlike those seen in chronic obstructive pulmonary disease. Echocardiography can reveal a decreased ventricular mass and mitral valve prolapse.
