Fourth Ventricular Medullomyoblastoma: A Case Report With Review Of Literature

Medullomyoblastoma (MMB) is a rare embryonal cerebellar neoplasm with both primitive neuroectodermal and striated muscle components. It occurs exclusively in children. It typically arises from the cerebellar vermis. There are only 54 case reports in the published literature. We report an additional case of a 7-year-old boy with fourth ventricular MMB that is unique in its site of origin, intratumoral hemorrhage and calcification.
