What is a pituitary tumor? Pituitary tumors are a group of tumors that occur from the anterior and posterior lobes of the pituitary gland and the remnant cells of the craniopharyngeal duct epithelium, and are the most common tumors in the saddle area. Pituitary tumors in children account for approximately 0.4-2.3% of intracranial tumors in children, and tumors are more likely to develop cystic changes, hemorrhage and necrosis than in adults. Since pituitary tumors in children are so important. Human growth and development cannot be regulated without endocrine hormones, which are produced through the entire axis of hypothalamus-pituitary-gland. The pituitary gland is an important endocrine organ of the human body, which contains several types of endocrine cells and secretes many endocrine hormones. If an endocrine cell grows adenoma, it can cause abnormal hormone secretion. One of them is the disruption of gonadotropin secretion, which can cause precocious puberty in children. What are the symptoms of precocious puberty in pituitary tumors? The symptoms of eosinophilic pituitary adenoma are hypopituitarism, growth arrest, failure to develop sexual characteristics, often accompanied by centripetal obesity and hypoglycemia. In contrast, eosinophilic adenoma mainly manifests as gigantism, which can coexist with acromegaly as the disease progresses. And in daily life, children with pituitary tumor may show sudden overgrowth, with obvious changes in body and appearance. Some people’s foreheads become wider, jaws protrude abnormally, noses become bigger, lips become thicker, fingers become obviously thicker, shoes they just bought soon and hats they wear feel tighter, frequently change larger models, or even have to be specially made, and some children even develop into giants. Then, besides the symptoms of precocious puberty introduced above, what other symptoms are there? When there are any symptoms, parents should pay attention to it? Headache: Usually caused by increased intracranial pressure. It often has no fixed location. The headache will gradually worsen with the development of the tumor and is accompanied by vomiting and head sweating in severe cases. Many infants and children are too young to express headache, but only cry or hit their head, parents should pay attention to them. Loss of vision or diplopia: More than 50% of children will show signs of vision loss, and a small percentage will show diplopia or strabismus. Unsteady walking: If the tumor grows in the posterior cranial fossa and involves or compresses the cerebellum or brainstem, it may lead to movement disorders, which usually manifest as unsteady standing and skewed gait. Vomiting: It is the most common symptom of pituitary tumor in children, with an incidence of 73% to 94%, and is often accompanied by dizziness, headache, nausea and neck stiffness. The duration of vomiting is not related to food intake and is intermittent and recurrent. Children are easily misdiagnosed as having gastrointestinal disorders. Pituitary tumors in children can be a very dangerous disease for children, and prevention of pituitary tumors in children is very important for their healthy growth. Therefore, it is important for parents to know how to prevent pituitary tumors. Parents must pay attention to their children’s health condition so that they can detect pituitary tumors in time and go to the hospital for regular treatment as soon as possible to avoid aggravation of the condition.
