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] 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]
| ' | MRI Component | Findings |
| 1 | T1 | Solid component iso- to hypointense |
| 2 | T1 C+ (Gd) | Solid component variable contrast enhancement |
| 3 | T2 | Hyperintense solid component |
| Variable signal in the cystic component | ||
| peritumoral flair/T2 edema is rare | ||
| 4 | T2 (GE/SWI) | Calcified areas shows blooming signal loss |
- 2. MRI scan of spinal cord is helpful in the diagnosis of spinal cord ganglioglioma. On MRI scan of spinal cord, it is characterized by:[2]
| ' | MRI Component | Findings |
| 1 | T1 | Mixed signal intensity |
| 2 | T1 C+ (Gd) | Patchy enhancement |
| 3 | T2 | High intensity |
| Surrounding edema is rare | ||
| 4 | Gradient echo | Calcification is common, low signal with blooming |
| 4 | T2 (GE/SWI) |
