MRI

Brain MRI scan is helpful in the diagnosis of ganglioglioma. On MRI, 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 (common) will show blooming signal loss
