Overview
Secondary Prevention
Effective measures for the secondary prevention of subependymal giant cell astrocytoma include:
- Brain imaging, preferably magnetic resonance imaging with and without contrast, should be performed every 1 to 3 years until the age of 25 years in every patient with tuberous sclerosis.
- Follow-up magnetic resonance imaging may not be needed every 3 years, but intervals may be prolonged in the presence of a stable lesion and a stable patient.
- Screening and follow-up scans frequency should be tailored according to various clinical factors.
- New onset of symptoms such as headache, visual complaints, nausea, vomiting, or increase in seizure activity should trigger an earlier MRI scan.
- Similarly, a growing subependymal giant cell astrocytoma should prompt a more frequent clinical and radiological follow-up.
