  Background.Myxoid meningioma as an unusual subtype of metaplastic meningiomas has been described.Histologically, it is designed when the meningothelial cells are embedded in a predominantly myxoid stroma.This article describes a new case in children and reviews the literature to further summarize the features of this variant.Case report.The present case was a 15-year-old female with a 20-day history of intermittent diplopia and blurred vision.Neuroimaging examinations demonstrated a right oval parafalx lesion, which was hypodense on computed tomography, hypointense on T1-weighted magnetic resonance image, hyperintense with a prominent peritumoural brain oedema on T2-weighted image, and remarkably enhanced by contrast medium.A right parieto-occipital craniotomy with gross total resection of the tumour was conducted and the postoperative pathology manifested it was a myxoid meningioma.Conclusions.Myxoid variant as a rare subtype of metaplastic meningiomas predominantly occurs in younger women.It may present completely different radiological appearances from those of general meningiomas.Total resection of the tumour may achieve good outcomes due to its bland pathological characteristics and clinical behaviour.
