Fig 4.

Acute internuclear ophthalmoplegia with abducens nerve palsy. MR imaging was performed on a 3T scanner. The punctate acute ischemic infarct in the left CN VI and the medial longitudinal fascicle, located in the inferior pons, was visible as hyperintensity (white arrow) on DW ZOOM-EPI (A) and as hypointensity (white arrow) on DW ZOOM-EPI ADC with an ADC of 0.707 × 10⁻³ mm²/second (B) but was not visible on standard DWI (C, with slightly different angulation compared with DW ZOOM-EPI) and on FLAIR (D). ADC in the right CN VI area was 0.948 × 10⁻³ mm²/second. A local microangiopathic origin was suspected. No cardiovascular embolic source was found.
