A 59-year-old presented with bilateral abducens nerve palsy and multiple facial bone fractures after a motor vehicle collision. (A) At the level of the upper midbrain, 3D-SPACE axial MRI shows hyperintensity in the right cerebral peduncle (arrowhead) consistent with contusion. At the level of the pontomedullary junction (B) and midpons (C), there is a nodular appearance of the avulsed right abducens nerve (circles) compared with normal left abducens nerve (arrows). (D) At the level of the Dorello canal both abducens nerves are normal (arrows).
3D: three-dimensional; SPACE: sampling perfection with application-optimized contrasts using different flip angle evolution; MRI: magnetic resonance imaging.
