Abstract:
Postoperative hemorrhages are relatively common complications of surgical procedures including craniotomies, and these typically occur at or near the operative site. Bleeding in remote areas (e.g., posterior fossa) after supratentorial craniotomy can occur and may be associated with a high morbidity and mortality. Although remote cerebellar hemorrhage after craniotomy is well described, remote pontine hemorrhage is less common. We describe a bilateral internuclear ophthalmoplegia due to an RPH after otherwise uncomplicated resection of a frontal meningioma. Clinicians should be aware that neuro-ophthalmic findings can occur from hemorrhages remote from the operative site.
