Precocious puberty in children is just that"Early development"Is it that simple? Not really! While parents are vigilant about the impact of precocious puberty on their children, they should also understand the possible ** behind their children's precocious puberty.
In recent years, studies have shown that the younger the age at which girls suffer from precocious puberty, the greater the possibility of imaging abnormalities, and although the incidence of precocious puberty in boys is low, more than 80% of them are organic, such as hypothalamus and pituitary tumors. Tumors are one of the most important causes of precocious puberty in children, and hypothalamic hamartomas are the type of tumors with the highest incidence of precocious puberty in children.
Hypothalamic hamartomaCan manifest as precocious puberty
Why would such a young child suffer from itHypothalamic hamartoma？Many parents will have such questions, and next, let's learn about hypothalamic hamartoma.
Hypothalamic hamartoma is not a real tumor, it refers to the normal tissues of some organs of the body in the process of development, the wrong arrangement, combination, tumor-like malformation, with the growth and development of the body and slowly grow, to a certain extent can be stopped. To put it simply, it's one"regiment"Normal brain tissue grows in the wrong place, on top of the hypothalamus.
The main clinical manifestations of hypothalamic hamartoma are precocious puberty, laughing epilepsy, cognitive dysfunction and other symptoms. For example, in this case, Xiaoxiao began to have epilepsy symptoms 2 years ago, and now she has precocious puberty, which is actually caused by hypothalamic hamartoma.
2. Why does hypothalamic hamartoma cause precocious puberty in children?
Some experts believe that there are gonadotropin-releasing hormone (GNRH) neurons in hypothalamic hamartomas, which are connected with gray nodules through axons to release hormones into the pituitary portal system, which directly affects the hypothalamus-pituitary gonadal axis, making sex hormones oversecreted and acting on target organs to cause precocious puberty. We can imagine the hypothalamus as a pomegranate, the flesh in it is neurons, put it in the mouth and bite through these flesh, the water produced is the gonadotropin-releasing hormone, these hormones affect the hypothalamus in the child's body, the pituitary gland gonadal axis, once this axis is activated, the child begins to develop, Xiaoxiao is because of this axis, causing the sex hormones in her body to change, resulting in precocious puberty.
In fact, in addition to hypothalamic hamartoma, brain tumors that cause precocious puberty in children include intracranial teratomas, hypothalamic germ cell tumors, pineal cysts, etc.
3. Parents should keep these special symptoms in mind
When parents find that their children are laughing, crying and convulsing for no reason, they should take their children to the hospital for a detailed examination as soon as possible; In addition, if the child has symptoms such as headache without obvious cause, enlarged head, unsteady walking, decreased vision, and polydipsia and polyuria, it may also be a sign of an intracranial tumor in the child.
