Meningioma growth

The mean volumetric growth rate was significantly greater than the planimetric growth rate, suggesting that volumetric measurement conveys more information and is superior in assessing tumor growth. This information could have clinical value in determining the frequency of follow-up imaging and the urgency of surgical intervention ¹⁾

Active monitoring seems a safe and appropriate first-linemanagement of incidental meningiomas. Intervention was avoided in > 40% with indolent tumors in a cohort. Treatment was not compromised by meningioma growth. Clinical follow-up seems sufficient beyond 5 years if self-limiting growth is established. Steady or accelerating growth warrant monitoring until they reach a stable state or intervention is initiated ²⁾
