Ventricular meningiomas are classified into WHO grade Ⅰ, Ⅱ, and Ⅲ according to the pathological findings, among which grade Ⅰ is mostly benign, and grade Ⅱ and Ⅲ may be malignant, and both benign and malignant tumors need to be treated aggressively. Ventricular meningioma is a kind of central nervous system tumor, which is more common in children, and can be classified into three grades such as Ⅰ, Ⅱ, Ⅲ, etc. Grade Ⅰ includes subventricular meningioma and muco-papillary ventricular meningioma, and grade Ⅱ is classic ventricular meningioma. Grade Ⅲ is mesenchymal ventricular meningioma. Among them, grade I is mostly benign, and grades II and III may be malignant, and the specific benign and malignant nature requires pathologic examination. The clinical manifestations of ventricular meningioma depend on the location of the tumor. When the tumor compresses the cerebrospinal fluid circulation pathway and forms obstructive hydrocephalus, headache, vomiting and visual impairment may occur. Involvement of cerebellar or brainstem structures may cause symptoms of ataxia, hemiparesis and cranial nerve damage. Symptoms such as epilepsy may also occur. Surgical resection is the mainstay of treatment for the tumor, which allows access to tumor tissue for diagnosis, as well as opening up cerebrospinal fluid pathways to relieve hydrocephalus and eliminate compression of fine neural structures. If you experience any of the above symptoms, or suspect a ventricular meningioma, it is recommended that you seek prompt medical attention.
