Overview
On head CT, some of the findings that are suggestive of subependymal giant cell astrocytoma include a heterogenous mass with uniform post contrast enhancement, enlargement of the ventricles, and iso- or slightly hypoattenuating to grey matter.
CT
Head CT scan may be helpful in the diagnosis of subependymal giant cell astrocytoma. Findings on CT scan suggestive of/diagnostic of subependymal giant cell astrocytoma include:[1][2][3][4]
- Round, heterogeneous mass
- Uniform post-contrast enhancement
- Cyst
- Calcification
- Iso- or slightly hypoattenuating to grey matter
- Enlargement of the ventricles
- Perilesional edema
