Coronal T2 view of a dilated MC in a patient with IIH. The black arrows represent the indentation of the Meckel cave. The white arrow shows the dilated cisternal space of the V3 segment of the left trigeminal nerve and points to the foramen ovale where the V3 nerve exits the intracranial space at the skull base. Dilation of this cisternal space may contribute to the indented appearance of the MC in patients with IIH.
