case_images: Magnetic resonance imaging (MRI) of the brain revealed a homogeneously enhancing 2.0 x 2.1 x 1.9 cm lesion in the right temporal lobe and right sphenoid wing, consistent with a meningioma [Figure 1].
case_images: (a) Axial, (b) sagittal, (c) coronal views of brain magnetic resonance imaging with gadolinium 12 years post gamma knife radiosurgery depicting an emergence of a ring-enhancing lesion adjacent to unevenly enhancing meningioma of the Sylvian fissure (asterisks of b and c). The meningioma remained stable or slightly decreased in size.
