Signo de la hoja de malvón y meningiomas en Resonancia Magnética

meningiomas are the most frequent primary intracranial tumors in adults. they are often a not difficult to diagnose finding, given their typical behavior on magnetic resonance imaging (mri) and computed tomography (ct). the description of this sign, based on the morphologic resemblance of this tumor to the geranium leaf, aims to be a useful tool for those cases where either the atypical presentation or the lack of appropriate sequences could hinder their characterization.
