Do meningiomas ever just dissolve and go away?

Meningiomas, which are typically benign tumors that arise from the meninges surrounding the brain and spinal cord, do not usually dissolve or go away on their own. While some small meningiomas may remain stable and not require treatment, they generally require monitoring or surgical intervention if they grow or cause symptoms. Spontaneous regression is extremely rare, and most cases require medical management. Regular follow-up with imaging is essential to track any changes in the tumor.
