Histology

MICROSCOPIC FEATURES: The  tumour  has a predominantly   papillary  architecture  with  cuboidal  or columnar  cells arranged around  cores  of basophilic  myxoid  material.  In  more cellular areas the  ependymal  cells form  perivascular   pseudorosettes.   Areas of haemorrhage and organising haematoma  are present.  There are also areas of degeneration  and  necrosis,  without  cellular  palisading.    Features of anaplasia,  including  hypercellularity,  microvascular   proliferation and mitotic activity, are not identified.

FINAL DIAGNOSIS: Myxopapillary ependymoma
