Fig 3.

Acute internuclear ophthalmoplegia with partial oculomotor nerve palsy. MR imaging was performed on a 3T scanner. The acute ischemic infarct in left CN III and the medial longitudinal fascicle was visible as a hyperintensity (white arrow) on DW ZOOM-EPI (A), as a hypointensity (white arrow) on DW ZOOM-EPI ADC (B) with an ADC of 0.6 × 10⁻³ mm²/second (compared with an ADC of 0.985 × 10⁻³ mm²/second in the normal right CN III), and as very faintly hyperintense on transverse FLAIR (D, white arrowhead). No pathologic findings were seen on standard DWI (C).
