A, Posterior globe flattening (white line), optic nerve protrusion (red arrows), and distension of the optic nerve sheath diameter (white line with arrowheads) in the right eye. B, Measurement technique applied to quantify the empty sella (white line with arrowheads). C, Measurement of the Meckel cave: The circled gray area highlights the width measurement (white line with arrowheads) on the right side. D, Standard measurement to assess cerebellar ectopia (white line with arrowheads). E, Measurement of the distance between the anterior horns of the lateral ventricles (red line with arrowhead) as well as the diameter of the third ventricle corpus (red arrows pointing to perpendicular red lines delimiting the third ventricle corpus). F, Measurement of the frontal and occipital subcutaneous fat (red lines). G, Anatomic course of the occipital emissary vein.
