A Pilocytic Astrocytoma Mimicking a Clinoidal Meningioma
Figure 1
(a) Axial, (b) coronal, and (c) sagittal T1-weighted MRI showing a homogenously enhancing lesion, measuring 2.9 × 3.0 × 2.0 cm in the right clinoidal region. There is probable extension into the right optic canal, sphenoid sinus, right temporal fossa, and possibly right cavernous sinus, suggestive of a right clinoidal meningioma.
