A 5-year-old boy has developed persistent food-seeking behavior over the past few months. His mother initially thought that the boy was undergoing a growth spurt, but despite how much she fed him he never seemed satisfied. He has now gained more than 4.5 kg (10 lb). The boy has also started complaining of a headache and nausea in the morning. His physical examination is significant for BMI of 32 kg/nv. Temperature is 37 .2 C (99 F), blood pressure is 100/70 mm Hg, pulse is 92/min, and respirations are 16/min . His pediatrician becomes concerned about possible central nervous system involvement.
