Abstract PDF: Facial palsy can be caused by central and peripheral causes, and it can also be caused by brain tumors or infarction. A 59-year-old male, who lost his right hearing 13 years ago due to Ramsay Hunt syndrome, visited our hospital with facial palsy and dizziness. Initial brain diffusion-weighted magnetic resonance imaging (MRI) showed no abnormal findings, and recurrent Ramsay Hunt syndrome or a neoplastic lesion in the internal auditory canal was suspected. After hospitalization, the patient was administered high-dose steroids, and the videonystagmography showed direction-changing gaze-induced nystagmus, so a brain MRI reexamination was scheduled. While waiting for MRI, the patient complained of neurological symptoms such as diplopia, and right lower pontine infarction was diagnosed on MRI. The patient was transferred to the neurologic department and was discharged on the 10th day after conservative treatment. During the 1-year follow-up, pontine infarction did not recur, and neurological symptoms such as facial palsy gradually improved.

Because numerous important nuclei and white matter tracts are concentrated in the narrow midbrain, the tiny lesion can result in various symptoms. The anatomy of the neural network and related structures in the midbrain is complex. The most frequent clinical manifestation of lesions involving the midbrain is an eye movement disorder associated with a nuclear or fascicular origin. We have described patients with acute midbrain stroke, characterized by rare neuro-ophthalmologic manifestations, which neurologists should consider during diagnostic investigations. Case 1 showed internuclear ophthalmoplegia with Horner syndrome. In case 2 showed isolated oculomotor palsy. The third patient presented Parinaud syndrome with an unusual lesion location. Notably, patients with midbrain infarction may present with specific signs and symptoms that are compatible with mesencephalic localization. The isolated or combined neuro-ophthalmologic signs and symptoms should be interpreted in the complex anatomical context described here and investigated by immediate brainstem neuroimaging analyses and careful neurologic examinations.
