When cerebral meningioma is found incidentally or presents without symptoms and without significant mass effect, the first-line management approach is distinct from that used for symptomatic or rapidly growing tumours. This protocol addresses that specific scenario.
Newly diagnosed or slow-growing cerebral meningioma — incidentally discovered or asymptomatic — with no mass effect. This includes suspected meningiomas and confirmed WHO grade 1 tumours.
In this setting, a structured imaging-based surveillance strategy is the initial management of choice, rather than immediate intervention. The full protocol specifies the schedule, duration, criteria for escalation, and decision points beyond the initial period.
