Overview
MRI
- Brain MRI may be helpful in the diagnosis of subependymal giant cell astrocytoma.
- Findings on MRI suggestive of subependymal giant cell astrocytoma are tabulated below:[1][2][3]

-
Two girls ([A] 9 and [B] 12 years old) with acute headaches and vomiting. On examination, both had papilledema. Brain magnetic resonance imaging shows ventricular subependymal giant cell astrocytomas with secondary hydrocephalus.[4]
-
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.[4]
-
Subependymal giant cell astrocytoma of the type associated with tuberous sclerosis are typically bulky, contrast-enhancing mass in the region of the foramen of Monro. Most overlie the head of the caudate nucleus. Foramen obstruction has produced hydrocephalus.[5]
