Abstract

Recently Brain CT and MRI have greatly contributed to the discovery of intracranial tumors including cysts which cause precocious puberty. Among many precocious pubetry patients that had previously been diagnosed as idopathic, a number of cases turn out the true precocious puberty caused by intracranial lesion.Authors experienced a case of true precocious puberty in a seven year old female whose vaginal bleeding appeared at age of five and she also had breast enlargement on admission. Pituitary microadenoma was found on her brain MRI and the microadenoma turned to be nonfunctional on hormonal tests.Following three does of decapety1-CR(LHRH Agonist), the vaginal bleeding was ceased and the deceleration of breast enlargement was noted. Her growth velocity was also affected but the further observation for final height would be warranted.
