What is medulloblastoma

summary

Wilms tumor is a disease that occurs in children. It is a kind of malignant glioma in posterior fossa, which is characterized by fast growth and difficult to remove completely. Let's talk about medulloblastoma.

What is medulloblastoma

First, medulloblastoma is a kind of malignant glioma in the posterior fossa of children named by Bailey and Cushing. Medulloblastoma cell morphology is very similar to the embryonic medulloblastoma, so use this name. Medulloblastoma is the most malignant glioma in the brain.

Second, medulloblastoma is a soft, fragile, solid tumor with recognizable boundary. The cut surface is purplish red or grayish red. Necrosis may occur in the center of larger tumor mass, cystic degeneration and calcification are rare. The tumors were mainly located in the vermis of cerebellum, protruding into the fourth ventricle and often invading the base of the fourth ventricle.

Third, medulloblastoma tends to diffuse and spread along the subarachnoid space. The adjacent pia mater of medulloblastoma is often infiltrated and forms a layer of milky white colloid like tissue on the surface of the brain. They spread along the subarachnoid space, and tumor metastases to the spinal canal and the surface of the brain; or they spread along the ventricle to the third ventricle.

matters needing attention

Patients with medulloblastoma can usually be treated by surgery, chemotherapy and radiotherapy. The average survival time after surgery is 0.9 years, so it is a terrible thing to have medulloblastoma, which requires us to pay more attention to our health in order to prevent this high-risk disease.
