Purpose: To report a case of transient diplopia and upgaze paresis in the setting of acute dorsal midbrain infarcts from a cervical vertebral artery dissection in an otherwise healthy man.
Observations: A 33-year old man presented to the ophthalmology urgent clinic with a 1 h history of blurred and double vision, asthenopia, and a mild focal left posterior headache. Ocular motility examination revealed a profound upgaze palsy and convergence-retraction horizontal jerk nystagmus in attempted upgaze that gradually improved over the course of 1 h.

Background: Respirator failure (RF) is a severe malignant complication in both lateral medullary infarction (LMI) and medial medullary infarction (MMI) patients. However, the differences in clinical and radiological manifestations associated with RF between patients with LMI and MMI have not been fully elucidated.
Methods: A total of 435 consecutive patients with MI within 7 days of onset in our institute were retrospectively enrolled from January 2017 to January 2024.

Posterior reversible encephalopathy syndrome (PRES) is a neurologic condition defined by symptoms and imaging findings secondary to vasogenic edema in the brain. Even though not all hypertensive individuals will progress to PRES, high blood pressure is the most frequent risk factor associated with the condition. The pathophysiology of PRES is not clearly understood, but the most accepted proposed mechanism focuses on the brain's inability to regulate cerebral blood flow through constriction or dilation of vessels during extreme blood pressure.

Background And Purpose: The dorsolateral portion of the caudal pons contains the vestibular nucleus (VN) and inferior cerebellar peduncle (ICP) that play important roles in conveying and processing vestibular and ocular motor signals. This study aimed to characterize ocular motor abnormalities along with their anatomical correlations in dorsolateral pons (DLP) lesions.
Methods: We analyzed clinical features, and results of neuro-otological evaluations and neuroimaging of 18 patients with unilateral DLP lesions (17 with DLP infarction and 1 with cavernous malformation) from among 506 patients with pontine infarction in a stroke registry.

Background: Acute brainstem infarction is associated with high morbidity and mortality, the integrity of corticospinal tract (CST) detected via diffusion tensor imaging (DTI) can assist in predicting the motor recovery of the patients. In addition to the damage caused by ischemia and reperfusion, sterile inflammation also contributes to the brain injury after stroke. However, the changes in CST integrity detected by DTI in acute brainstem infarction have yet to be fully elucidated, and it is still unclear whether sterile inflammation can cause damage to the CST.
