Central precocious puberty due to hypothalamic hamartoma in Cameroon

Hypothalamic hamaitoma is ati uncommon cause of central precocious puberty and sometimes of gelastic epilepsy and delayed development. The purpose of this report is to describe a case of central precocious puberty in an 18-month-old girl who was referred to our department for further investigation of vaginal bleeding that had appeared during the 8th month of life. The patient's puberty was compatible with Tanner stage .3, her psychomotor development was normal, and epilepsy was not observed. Diagnosis was based on abnormal hormonal workup findings and discovery of a hypothalamic hamiutoma on brain magnetic resonance imaging. Neurosurgery was not performed. Administration of long-acting gonadotropin releasing honnone analog to slow puberty led to clinical improvement. Hypothalamic hamartoma mu.st always be suspected in case of central precocious puberty Although magnetic resonance imaging is the most reliable modality, it is not always available nor affordable in low-income countries. Neurosurgery is not indicated in patients without epileptic .seizure. Gonadotropin releasing hormone agonists are usually indicated to slow down puberty and improve the adult height. However, the cost is prohibitive in developing countries.
