Are meningiomas serious?

Whether meningioma is serious depends on the patient's specific condition. If there are no clinical symptoms, it is generally not serious. However, if symptoms appear, the condition is considered more serious and requires timely surgical treatment.

1. Not serious: Most cases are not serious and are considered common primary intracranial tumors. If the meningioma is less than 2 cm, asymptomatic, located clearly at the edge, and proven to be benign after biopsy, the tumor typically has a longer survival period, low invasiveness and recurrence rate, and good tissue differentiation. Most patients achieve good therapeutic outcomes after meningioma resection surgery and can recover to a completely normal state; thus, the condition is generally not considered serious.

2. Serious: Anterior, middle, and posterior skull base meningiomas often involve important blood vessels and nerves at the skull base, making surgical removal challenging. Meningiomas located adjacent to the cavernous sinus in the middle skull base, the petroclival region of the posterior skull base, or those extending across the middle and posterior skull base are relatively difficult to treat. Patients may experience complications and sequelae related to cranial nerve damage after surgery.
