Hypothalamic hamartoma associated with central precocious puberty and growth hormone deficiency.

Hypothalamic hamartomas (HHs) are tumors generally associated with isolated central precocious puberty (CPP). To our knowledge, we report a unique case of a girl with HH associated with CPP and growth hormone deficiency. This case highlights the complex interaction between HHs and the hypothalamic-pituitary-gonadal axis. It also emphasizes the value of close follow-up of growth velocity in these patients even after treatment of the CPP.
