Overview

On MRI of the brain, ganglioglioma is characterized by iso- to hypointense solid component on T1, variable contrast enhancement of solid component on T1 C+ (Gd), hyperintense solid component and variable signal in cystic component on T2, and calcification on T2 (GE/SWI).[1] On MRI of the spinal cord, ganglioglioma is characterized by mixed signal intensity on T1-weighted images, high intensity on T2, patchy enhancement on T1 C+ (Gd), and calcification with low signal blooming on gradient echo.

MRI

  • 1. Brain MRI scan is helpful in the diagnosis of cerebral ganglioglioma. On MRI of the brain, ganglioglioma is characterized by:[1]
MRI Component Features
T1​
  • Solid component iso- to hypointense
T1 C+ (Gd)
  • Solid component variable contrast enhancement
T2
  • Hyperintense solid component
  • Variable signal in the cystic component
  • Peritumoral flair/T2 edema is rare
T2 (GE/SWI)
  • Calcified areas shows blooming signal loss
  • 2. MRI scan of the spinal cord is helpful in the diagnosis of spinal cord ganglioglioma. On MRI of the spinal cord, ganglioglioma is characterized by:[2]
MRI Component Features
T1​
  • Mixed signal intensity
T1 C+ (Gd)
  • Patchy or no enhancement
T2
  • High intensity
  • Surrounding edema is rare
Gradient echo
