Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect multiple organ systems. Cerebral aneurysm formation is a rare central nervous system manifestation of SLE and tends to present as subarachnoid hemorrhage. Here, we report a 34-year-old woman with SLE complicated by a thrombosed aneurysm that had arose at the origin of a perforating artery, thereby causing obstruction of the artery and subsequent development of pontine infarction. Detailed examination of thin-slice CT and magnetic resonance imaging scans led to the correct diagnosis of uncommon cause of stroke.

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.

Objectives: Early clinical worsening (ECW) in acute isolated pontine infarcts (AIPI) is frequent, associated with poor prognosis, and its predictors have not been adequately clarified. A possible role of dolichoectatic basilar artery (BA) anatomy in ECW in patients with AIPI is herein studied.
Methods: In 146 AIPI patients, infarcts were grouped into tegmental, lateral, anterolateral, anteromedial horizontally; and low, mid, mid-up, and upper pontine vertically.
We report a case of acute ischemic stroke presenting as wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) syndrome. A 71-year-old woman experienced transient diplopia, followed by the sudden onset of binocular misalignment, gait instability, and nausea. Neurological examination demonstrated exotropia and bilateral adduction impairment, consistent with WEBINO syndrome.
