Overview
Gross appearance
- Typically metastases are sharply demarcated from the surrounding parenchyme and usually there is a zone of peritumoral edema out of proportion with the tumor size.
- Common intracranial sites associated with subependymal giant cell astrocytoma include:[1]
- Cerebrum (80%)
- Cerebellum (15%)
- Brain stem (5% )
Microappearance
Typically well-demarcated with the exception of melanoma metastases.
