====== Medulloblastoma Radiographic Features ======


[[Medulloblastoma Classification]] presents many faces in medical imaging.

[[Location]] is the key to this approach

__[[cerebellar peduncle]]/[[foramen of Luschka]]__

very likely [[Medulloblastoma, WNT-activated]] and therefore best prognosis

__[[cerebellar hemisphere]]__

very likely SHH subgroup and therefore intermediate prognosis
likely desmoplastic/nodular/medulloblastoma with extensive nodularity (MBEN)

__midline__

may be [[Group 3 medulloblastoma]], [[Group 4 medulloblastoma]] or [[Medulloblastoma, SHH-activated]]

typically infants with a tumor with ill-defined margins but prominent enhancement: likely [[Group 3 medulloblastoma]] or [[Medulloblastoma, SHH-activated]] and therefore worst prognosis

typically children with a tumor with well-defined margins but mild or no enhancement: likely [[Group 4 medulloblastoma]] and therefore slightly better prognosis

adults with variably defined and variably enhancing tumors: most likely [[Medulloblastoma, SHH-activated]]; hemorrhage raises the probability of group
