Medulloblastoma of brain

Description

A malignant, invasive embryonal neoplasm arising from the cerebellum. It occurs predominantly in children and has the tendency to metastasize via the cerebrospinal fluid pathways. Signs and symptoms include truncal ataxia, disturbed gait, lethargy, headache, and vomiting. There are four histologic variants: anaplastic medulloblastoma, desmoplastic/nodular medulloblastoma, large cell medulloblastoma, and medulloblastoma with extensive nodularity.
