Idiopathic intracranial hypertension: Imaging and clinical fundamentals

Figure 5 Meningoceles. A: Coronal T2-weighted magnetic resonance image is shown displaying a normal temporal bone; B and C: A coronal T2-weighted image (B) and corresponding coronal computed tomography (CT) image (C) of a patient with idiopathic intracranial hypertension demonstrates meningeal protrusions in the sphenoid wings, bilaterally (dashed circles), consistent with meningoceles; D and E: An axial T2-weighted image (D) and corresponding axial CT image (E) of a different patient with idiopathic intracranial hypertension also demonstrate meningeal protrusions (dashed circles), most evidently on the right sphenoid wing than on the left, findings that are consistent with meningoceles.
