MRI

Brain MRI scan is helpful in the diagnosis of ganglioglioma. On MRI brain, it is characterized by:

• T1
  • Solid component iso- to hypointense
• T1 C+ (Gd)
  • Solid component variable contrast enhancement
• T2
  • Hyperintense solid component
  • Variable signal in the cystic component(depending on amount of proteinaceous material or presence of blood products)
  • Peritumoral FLAIR/T2 edema is rare
• T2* (GE/SWI)
  • Calcified areas shows blooming signal loss
