Treatment of Cerebral Meningioma in Elderly or Critically Ill Patients with Contraindication to Surgery
Not every patient with a symptomatic intracranial meningioma is a candidate for open surgery. When the clinical condition is poor — whether due to advanced age, critical illness, or a relative or absolute surgical contraindication — and the tumor is small and without significant mass effect, a distinct evidence-based management path applies.
Clinical scenario
Symptomatic intracranial meningioma with a tumor diameter of 3 cm or less and no mass effect, in a patient who is elderly, critically sick, or has a relative or absolute contraindication to surgery.
In this setting, surgery is not the preferred first step — and the evidence supports a non-surgical alternative that achieves comparable local control in well-selected patients.
Approach
Radiation-based therapy — specifically a focused radiosurgical approach or fractionated radiotherapy — is the intervention of choice in this scenario, applied under carefully defined criteria regarding tumor size, location, and the absence of a tissue-sampling requirement.
The full protocol specifies the selection criteria, modality considerations, and follow-up framework — access it below.
Treatment goal: Long-term local tumor control on imaging — sustained disease stabilisation without surgical intervention.
