Overview
MRI
Brain MRI may be helpful in the diagnosis of ganglioglioma.
- In MRI imaging, ganglioglioma may appear as solid or cystic lesions.
- MRI T1-weighted images show a hypointense mass.
- MRI T2-weighted and FLAIR images show a well-circumscribed hyperintense mass.
- Ganglioglioma often does not enhance with intravenous gadolinium. However, some tumors have mild diffuse or patchy enhancement without ring appearance.
- Conventionally they are sharply demarcated, but some are infiltrative and are indistinguishable from diffuse gliomas.
- Anaplastic ganglioglioma is frequently infiltrative on MRI and is associated with a higher degree of gadolinium enhancement.
- Overall, diagnosis might be suggested by clinical presentation and MRI characteristics, but the definitive diagnosis is only made by histopathological examination of the tumor. Review : [1] [2] [3]
