Abstract:
Bilateral trochlear nerve palsies without other signs of dorsal midbrain syndrome following spontaneous midbrain haemorrhage is extremely rare. We report the case of a 37-year-old man with bilateral trochlear nerve palsies causing superior oblique palsies (SOP) from dorsal midbrain haemorrhage which recovered with conservative management. The report highlights the need for imaging in patients with spontaneous bilateral superior oblique (BSO) motility deficits.
