Medulloblastoma

Medulloblastomas arise from immature, undifferentiated cells in the cerebellum. Histologically, a characteristic appearance is that of cells with round or elongated shapes that frequently form rosettes and (around blood vessels) pseudorosettes.

About 20% of pediatric brain tumors are medulloblastomas that in two thirds of cases arise during the first 15 years of life. The younger the child, the greater the aggressiveness of growth expected. There is a very high rate of local metastasis via the cerebrospinal fluid in the subarachnoid space, and a high rate of extraneural metastasis (30%). Sixty-five percent of cases are male, and in 90% of cases, the tumors arise in the posterior cranial fossa, most commonly in the cerebellar vermis.
