Overview
On brain MRI, some of the findings that are suggestive of subependymal giant cell astrocytoma include T1 isointense and hypointense signal enhancement, T2 isointense and hyperintense signal enhancement, and enlargement of ventricles.
MRI
Brain MRI may be helpful in the diagnosis of subependymal giant cell astrocytoma. Findings on MRI suggestive of/diagnostic of subependymal giant cell astrocytoma include:[1][2]
- Well circumscribed mass
- Perilesional edema
- T1 isointense and hypointense signal enhancement
- T2 isointense and hyperintense signal enhancement
- Calcification
- Cyst
- Enlargement of ventricles
- Homogenous postcontrast enhancement
Serial MRI's every 1-3 years is recommended in asymptomatic patients younger than 25 as tumor growth is more common in these patients.[1]
