Hypothalamic hamartoma causing precocious puberty treated by surgery: case report.
A 6-year-old girl was treated for precocious puberty secondary to a hypothalamic hamartoma by resection of the tumor. When she was six months old, her parents noticed incipient pubic hair and menses accompanied by breast development. Computed tomography was judged as normal. The girl was treated with monthly gonadotropin-releasing hormone analogue injections until 6 years of age, when magnetic resonance imaging (MRI) demonstrated a pedunculated isodense mass below the tuber cinereum. The hamartoma was totally removed using microsurgery. The symptoms and signs of precocious puberty disappeared after surgery. Follow-up MRI 1 year later showed no remaining tumor.
