Overview
Brain MRI is helpful in the diagnosis of subependymal giant cell astrocytoma. On MRI, subependymal giant cell astrocytoma is characterized by hypo- to isointensity on T1-weighted imaging and hyperintensity on T2-weighted imaging. There may be marked enhancement on contrast administration.[1]
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:[2]
- T1 isointense and hypointense signal enhancement.
- T2 isointense and hyperintense signal enhancement.

![This 6-year-old girl had a growing but asymptomatic tumor. (A) Her screening magnetic resonance imaging at age 2 revealed a subependymal giant cell astrocytoma with mild enlargement of the right lateral ventricle. (B) By age 6 years, the lesion had enlarged markedly.[3]](/images/7/7f/Subependymal_giant_cell_astrocytoma_MRI_2.jpg)
