Velocity and pattern of growth of intracranial meningiomas.

Objective: The authors' aim was to assess the velocity and pattern of growth of meningiomas and to correlate the kinetics of tumor growth with their previously reported two-item radiological risk stratification and CNS WHO grade (5th edition, 2021).

Methods: The authors performed a serial volumetric analysis of meningiomas diagnosed radiologically at their institution between 2003 and 2015. The primary endpoint was velocity of diametric expansion (VDE), which represents the slope of the linear regression of the mean tumor diameter against time.

Natural history of meningiomas: a serial volumetric analysis of 240 tumors.

Objective: The management of asymptomatic intracranial meningiomas is controversial. Through the assessment of growth predictors, the authors aimed to create the basis for practicable clinical pathways for the management of these tumors.

Methods: The authors volumetrically analyzed meningiomas radiologically diagnosed at their institution between 2003 and 2015.
