Abstract
Medullomyoblastoma (MMB) is a rare variant of medulloblastoma, a member of the family of central nervous system (CNS) embryonal tumors. The outcome of standard therapy for CNS embryonal tumors is often unpredictable in the setting of MMB. Here, we present the clinical course and treatment of an almost 4-year-old girl with MMB that was characterized by MYC amplification, isochromosome 17q and large cell/anaplastic histopathology.
