Multiple meningoencephalocoeles are noted:
- Left temporal lobe into the left sphenoid sinus, containing the uncus and the tip of the left temporal horn. The temporal horn and the entorhinal sulcus are distorted, pulled anteromedially in direction of the herniation, with small focus of T2 hyperintensity abutting ventricle.
- Left frontal sinus and anterior enthmoidal air cells (separate bony defects) with the anterior aspect of gyrus rectus within the frontal sinus with distortion and subtle T2 hyperintensity involving the nearby anteromedial frontal cortex.
- Right frontal sinus and right anterior ethmoid sinus (separate bony defects).
Additionally there are signs of intracranial hypertension:
- enlarged Meckel's caves bilaterally
- partially empty fossa
- prominent bilateral optic nerve sheathes
