Overview
Diagnostic Study of Choice
Study of choice
There is no single diagnostic study of choice for the diagnosis of subependymal giant cell astrocytoma, but subependymal giant cell astrocytoma can be diagnosed based on contrast enhanced MRI and CT scan.[1]
Diagnostic results
The following finding(s) on performing MRI is(are) confirmatory for subependymal giant cell astrocytoma:[1][2]
- T1 isointense and hypointense signal enhancement
- T2 isointense and hyperintense signal enhancement
- Homogenous postcontrast enhancement
