Definition / general
  • Superficial cerebrocortical tumour with features of infiltrating astrocytoma and ependymoma
  • Relationship to ependymoma is unclear
  • Primarily children and young adults
  • Wide age range (2 to 70 years, mean 17 years)
  • Affect both sexes equally
Clinical features
  • Seizures are characteristic
  • WHO grade I
  • Criteria for higher grade lesions are unclear
Radiology description
  • Well delineated, solid, hyperintense, nonenhancing cortical lesions
  • Stalk-like extension to adjacent ventricle is diagnostic

Prognostic factors
  • Generally favorable with rare recurrence
Case reports
  • Surgical excision
  • Role of chemo or radiotherapy is unclear
Gross description
  • Ill defined, firm
Microscopic (histologic) description
  • Infiltrative, monomorphous, bipolar spindled cells arranged in angiocentric pattern about cortical blood vessels
  • Also ependymoma-like pseudorosettes, subpial palisading, accumulation of tumor cells, miniature schwannoma-like nodules
  • Usually no mitoses, no vascular proliferation, no necrosis
  • Mitotically active lesions are associated with increased risk of recurrence
Positive stains
  • EMA (dot-like microlumina, focal surface), variable GFAP
