Description
Summary:A 22-year-old male was referred from the medicine department with the chief complaint of double vision for 2 months. The patient had suffered from dengue viral hemorrhagic encephalitis for 2 months for which intensive medical care was given. On ocular examination, both eyes (OU) showed limited adduction with contralateral abducting nystagmus on attempted horizontal gaze. Magnetic resonance imaging of brain showed pontine and midbrain hemorrhages which involved the region of medial longitudinal fasciculus and caused bilateral internuclear ophthalmoplegia (INO). Bilateral INO is very rare and most commonly caused by multiple sclerosis. The presentation of dengue fever causing midbrain and pontine hemorrhages which resulted in bilateral INOs has not been previously reported, to our knowledge.
