Midbrain Infarction Causing Oculomotor Nerve Palsy and Ipsilateral Cerebellar Ataxia

Midbrain infarction causing oculomotor nerve palsy and ipsilateral cerebellar ataxia.

We herein report the case of an 81-year-old woman with midbrain infarction causing pupil-sparing oculomotor nerve palsy with ipsilateral cerebellar ataxia. The lesion was located at the rostral end of the decussation of the superior cerebellar peduncle touching the dorsal side, further caudal and dorsal to causal lesions of Claude's syndrome, which presented as oculomotor palsy and contralatera...

Unilateral oculomotor nerve palsy, ataxia and Parinaud’s syndrome caused by ventral midbrain hemorrhage

We report a patient with unilateral midbrain hemorrhage which caused ipsilateral complete oculomotor nerve palsy with pupillary involvement, contralateral upgaze paresis, contralateral limb ataxia and Parinaud’s syndrome. CT scan and MRI brain demonstrated a hemorrhage in the left paramedian midbrain probably involving the oculomotor fascicles; extension of the hemorrhage to the most rostral mi...

Combined Ipsilateral Oculomotor Nerve Palsy and Contralateral Downbeat Nystagmus in a Case of Cerebral Infarction

We report a patient with acute cerebral infarction of the left paramedian thalamus, upper mesencephalon and cerebellum who exhibited ipsilateral oculomotor nerve palsy and contralateral downbeat nystagmus. The site of the infarction was considered to be the paramedian thalamopeduncular and cerebellar regions, which are supplied by the superior cerebellar artery containing direct perforating bra...

Traumatic Oculomotor Nerve Palsy

Oculomotor nerve palsy generally presents with mydriasis, blepharoptosis, and impairment of extraocular muscle movement. The incidence of primary traumatic oculomotor nerve palsy in craniocerebral trauma is approximately 1.2% [1]. The causes of oculomotor nerve palsy are congenital, traumatic, vascular, migrainous, and parainfectious. Especially in children, it is often caused by congenital fac...
