Overview
On MRI 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]
MRI
Brain MRI scan is helpful in the diagnosis of ganglioglioma. On MRI brain, it is characterized by:[1]
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
