Discovery of the day
This retrospective cohort study demonstrates that meningiomas arising after childhood scalp irradiation for tinea capitis constitute a clinically distinct subgroup with a significantly poorer volumetric response to stereotactic radiosurgery compared with sporadic tumors. Among 204 patients analyzed, multivariable regression revealed that prior tinea capitis irradiation independently predicted a +38.7% relative volume change (P = .026), despite similar baseline tumor volumes and surgical resection rates between groups. These findings challenge the assumption that radiation-induced meningiomas respond equivalently to SRS, and the identification of this treatment-resistant, multifocal phenotype carries direct implications for prognostic counseling and individualized management strategies in neuro-oncology practice.
