Gliomatosis cerebelli, an infantile cerebellar neoplasm that exhibited diffuse infiltration without forming a mass

摘要

Brain neoplasms are the second most common type of infantile neoplasm after infantile leukemia, and the commonest form of infantile solid neoplasm, with the highest mortality. They frequently appear in the infratentorial cavity, and although astrocytoma is the most common histopathological type, other neoplasms that are also more common in infancy than adulthood (such as medulloblas-toma, ependymoma, and choroid plexus papilloma) are also seen [1-3]. A case in which a malignant neoplasm appeared in the cerebellum of a young child and showed prominently diffuse infiltration without forming a mass is reported and discussed below.
