title: Giant solitary fibrous tumour of the meninges: MR-pathological correlation.
abstract: The authors present the clinical, MR imaging and pathological features of the largest intracranial solitary fibrous tumour of the meninges ever reported in the literature. This well-circumscribed dural-based tumour strikingly demonstrated two different solid components. The first one demonstrated a suggestive T2 hypointensity that strongly enhanced after gadolinium administration while the other showed more classic homogeneous T2 hyperintensity and mild enhancement. These two components were also identifiable on the pathological examination, allowing an interesting imaging-histological correlation. Differential diagnoses of this rare extra-axial lesion are discussed.
