Hypothalamic hamaomas and gangliocytoma may arise from astrocytes, oligodendrocytes, and neurons with varying degrees of differentiation. These tumors may overexpress hypothalamic neuropeptides, including GnRH, GHRH, and CRH. With GnRH-producing tumors, children present with precocious pubey, psychomotor delay, and laughing-associated seizures. Medical treatment of GnRH-producing hamaomas with long-acting GnRH analogues effectively suppresses gonadotropin secretion and controls premature pubeal development. Ref:Melmed S., Jameson J.L.
