Meningiomas are rare in childhood, accounting for only 0.4% to 4.6% of intracranial tumors in children. Meningioma in children and meningioma in adults are both brain tumor diseases, but some people may think that the difference between these two diseases can be fully understood from the wording, that is, the two diseases are different in terms of the people who develop them, and meningioma in children develops in children while meningioma in adults develops in adults. In fact, the difference between these two brain tumor diseases is much more than that. The differences between meningioma in children and meningioma in adults are generally as follows: Meningioma in adults is mostly benign and sarcoma-like changes are rare, while malignant meningioma in children is more common than in adults. Lateral ventricular triangle and posterior cranial sulcus: In adults, meningiomas are more likely to be located on the synovial surface of the brain or next to the sagittal sinus, while in children they are more likely to be located in the lateral ventricular triangle and posterior cranial sulcus. Comorbid neurofibromas: Patients with meningiomas in children tend to have comorbid neurofibromatosis. Endothelial and vascular endothelial cell types are common: Fibrous and gravel types are common in adults, while endothelial and vascular endothelial cell types are common in children. Tumors often grow faster: adult meningiomas tend to grow slowly and have a longer course, whereas in children, tumors often grow faster and can be huge at the time of presentation. Meningiomas are more often unadherent to the dura mater: In adults, meningiomas are more often adherent to the dura mater; in children, there are few tumors that are unadherent to the dura mater, which may be related to the fact that the tumor comes from the arachnoid or soft meninges. Cystic changes and hemorrhage are common: Meningioma calcification is rare in children, while cystic changes and hemorrhage are common. Higher recurrence rate: Meningiomas in children have a higher recurrence rate after surgery than in adults. In general, intracranial arachnoid granules and arachnoid villi are the most common sites of meningioma; parsagittal sinus, cerebral convexity, and pars falciformis are also more common; pterygoid crest, saddle node, olfactory groove, pontocerebellar angle and cerebellar curtain are less common; meningiomas growing in the ventricles are rare. The occurrence of meningioma may be related to certain internal environmental changes and genetic variants, not a single factor, but may be related to cranial trauma, radiation exposure, viral infection and combined bilateral auditory neuroma.
