Abstract: Morphological and fractal properties of the tumor interface serve as key descriptors of tumor growth dynamics. For meningiomas, previous studies have highlighted growth patterns that diverge from the proliferative-invasive model typically associated with malignant brain tumors, such as gliomas. In this work, two distinct approaches are employed to investigate the scale-dependent properties of meningioma growth. Initially, longitudinal volume data sets for meningiomas are analyzed, employing an allometric growth model to distinctly differentiate between asymptomatic and anaplastic (petroclival) meningiomas. Secondly, a scaling analysis of tumor interfaces extracted from contrast-enhanced MRI established a clear distinction among tumor grades. This analysis not only confirmed previous findings regarding tumor growth dynamics but also revealed significant morphological and scaling properties essential for characterizing tumor grades.
