Anorexia nervosa and brain tumor in a 14-year-old girl.

A 14-year-old girl with anorexia nervosa (AN) was found to have an intracranial neoplasm. Atypical psychological symptoms prompted further evaluation, including electroencephalogram and neuroimaging, which revealed a sellar and suprasellar mass. This patient had an eating disorder and a brain tumor, which appear to be two unrelated conditions.
