Overview

Head CT scan may be diagnostic of glioma. The CT scan findings of glioma vary with the tumor grade and type.[1][2][3][4][5][6]

CT

  • Head CT scan may be diagnostic of glioma.
  • The CT scan findings of glioma vary with the tumor grade and type. Common findings are listed below:[1][2][3][4][5][6]
Type of glioma CT scan findings

Pilocytic astrocytoma

1. Large cystic component with a brightly enhancing mural nodule (67%)
  • Non enhancing cyst wall (21%)
  • Enhancing cyst wall (46%)
2. Heterogeneous, mixed solid and multiple cysts and central necrosis (16%)
3. Completely solid (17%)

Low-grade astrocytoma

1. Isodense or hypodense
2. Positive mass effect
3. No enhancement
4. Calcification is rare
5. Cystic component

Anaplastic astrocytoma

1. Variable enhancement
2. Regions of low attenuation
3. Positive mass effect

Glioblastoma multiforme

1. Irregular thick margins: iso- to slightly hyperattenuating (high cellularity)
2. Irregular hypodense centre representing necrosis
3. Marked mass effect
4. Surrounding vasogenic edema
5. Hemorrhage
6. Calcification is rare

Oligodendroglioma

1. Hypodense to isodense
2. Calcification (70-90%)
3. Hemorrhage
4. Overlying skull may show pressure erosion

Ependymoma

1. Coarse calcification is common (50%)
2. Cystic areas (50%)
3. Iso- to hypodense solid component
4. Heterogeneous enhancement
5. Hemorrhage
