Pediatric Gliomatosis Cerebri

  • Etiology: diffuse glioma
  • Imaging: infiltrate through white matter, cross midline, architecture otherwise preserved (less mass effect than expected for lesion size)

Radiology Cases of Gliomatosis Cerebri

MRI of gliomatosis cerebri
Three contiguous axial FLAIR MRI images (above left, above right, below left) show a high signal intensity infiltrative mass without much mass effect centered in the left frontal lobe which crosses the corpus callosum into the right front lobe and right central white matter. Axial T1 MRI with contrast of the brain (below right) shows the mass to have faint enhancement.
