On head CT scan, ganglioglioma is characterized by iso- or hypodense, [[calcification]], bone remodelling, and enhancement of solid non-calcified component.

Overview

CT

  • Gangliogliomas lack distinctive features by CT scan. The tumor may present as:
  • Solid or cystic mass
  • Isodense or hypodense[1]
  • Ganglioglioma might have calcifications which are easily detected on CT scan.[2]
