Symptoms of medulloblastoma in children, be alert after reading this!

After the baby is born, a detailed physical examination will be conducted. If the baby has medulloblastoma, the symptoms are quite obvious. In particular, professional medical examinations can detect the disease and understand the severity of the disease.

1. Symptoms:

The main manifestations are cerebellar symptoms such as increased intracranial pressure and ataxia. Those that invade the brainstem often have diplopia and multiple cranial nerve disorders. Cerebellar tonsillar herniation often causes neck stiffness and torticollis. Because most tumors obstruct the fourth ventricle, intracranial pressure increases, and the average course of the disease is about 4 months.

1. Increased intracranial pressure manifests itself as headache, vomiting and optic disc edema. In this group, headache accounted for 76.6%, vomiting accounted for 95%, and optic disc edema accounted for 72.1%. Younger children may have cranial suture dehiscence.

2. Signs of cerebellar damage mainly include truncal ataxia, unstable gait and standing shakiness caused by damage to the cerebellar vermis, and positive Romberg sign. Tumor compression of the medulla oblongata may cause swallowing choking and pyramidal tract signs. Two-thirds of the children show decreased muscle tone and tendon reflexes. Some patients have nystagmus and limb ataxia. In this group, 88.3% of the subjects had cerebellar signs.

2. Diagnosis:

If preschool or school-age children, especially boys, have unexplained headaches and vomiting, followed by unsteady gait, nystagmus, and diplopia, the possibility of medulloblastoma should be considered first, and further neuroradiological examinations should be performed to confirm the diagnosis. For some children, the diagnosis can be confirmed by finding exfoliated tumor cells in the cerebrospinal fluid. Medulloblastoma is prone to dissemination and metastasis. If the posterior cranial fossa tumor spreads intraventricularly, the disease can be diagnosed before surgery.

3. The tumor is highly malignant, grows fast, and has a short course. The average time from onset to medical treatment is about 4 months, the shortest is 10 days, and the longest is about 1 year. The main manifestations are symptoms of increased intracranial pressure and cerebellar symptoms. Myeloid blasts are a very primitive amygdala cell. In human embryos, it is only seen in the posterior medullary velum, which is consistent with the fact that medulloblastoma often occurs in the inferior cerebellar vermis. Medulloblastoma is the most malignant intracranial glioma.

4. If preschool or school-age children, especially boys, have unexplained headaches and vomiting, followed by unsteady gait, nystagmus, and diplopia, the possibility of medulloblastoma should be considered first, and further neuroradiological examinations should be performed to confirm the diagnosis. For some children, the diagnosis can be confirmed by finding exfoliated tumor cells in the cerebrospinal fluid. Medulloblastoma is prone to dissemination and metastasis. If the posterior cranial fossa tumor spreads intraventricularly, the disease can be diagnosed before surgery. It is recommended to go to the hospital for examination to determine the cause of the disease.
