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 scan of 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.^[2]

MRI

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


{{fontcolor\|#FFF\|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
