Magnetic resonance imaging (MRI) of brain revealed herniation of the brain along with the dura through a defect in the left greater wing of the sphenoid into the pterygopalatine fossa and retromaxillary space [Figures 1-3]. Computed tomography (CT) Brain & CT cisternography (Figures 3-5) revealed bony defect in the middle cranial fossa in the left greater wing of sphenoid with CSF leak.
