“…Cerebrovascular accidents often involve the circle of Willis, a vascular plexus formed by the anterior internal carotid artery (ICA) and posterior cerebral (vertebral) vasculature. Within the posterior cerebral vasculature, occlusion or hemorrhage affecting the vertebral artery (VA) or the posterior inferior cerebellar artery (PICA) may give rise to the clinical syndrome known as lateral medullary syndrome (LMS) or Wallenberg syndrome [ 2 ].…”

“…Therefore, a patient presenting with LMS typically exhibits a loss of pain and temperature sensation on the ipsilateral face and contralateral body. Additionally, they may display ipsilateral cerebellar ataxia, leading to a propensity to fall toward the side of the lesion, and ipsilateral dysarthria and dysphagia, often manifesting as a loss of the gag reflex on the same side [ 2 , 4 ].…”

In this case, a 61-year-old patient presented with Horner’s syndrome of the left eye, left-sided truncal ataxia, left-sided pain/paresthesia of the face as well as right-sided loss of pain and temperature of the arms and legs. MRI findings displayed a clear 4 mm acute left lateral medullary infarct of the left posterior inferior cerebellar artery (PICA) vascular territory, indicative of lateral medullary syndrome (LMS). The presence of pre-existing medical conditions such as uncontrolled diabetes, late-stage syphilis, and a mechanical aortic valve complicated this clinical picture. The presence of ipsilateral corticospinal deficits in this patient revealed Opalski syndrome, a rare variant of LMS. This case report highlighted the importance of correlating imaging and physical examination of stroke findings.

value. To derive the modiﬁed Friedmann ﬁeld equations (FFEs), we use entropies and the ﬁrst law of thermodynamics. Thus, even in the presence of the typical interaction between the Ricci scalar and baryon current, this results in non-trivial modiﬁcations to the mass density and pressure content of the universe, which provides a viable mechanism allowing for baryogenesis. Finally, we show that even in the radiation-dominant era baryon asymmetry factor (BAF) is non-zero. We conclude, BE parameter 0 ≤ ∆ < 1, SME parameters R and δ with positive δ ≥ 4.2 × 1038 (keeping ﬁxed R = 1) while at constant δ = 9 × 1028 for all values of R and for the generalized entropy parameter positive β ≤ 2.4 × 10−28 (ﬁxing γ = α = 5); α ≤ 3.5 × 10−23 (for γ = 1.2 and β = 3) and γ ≥ 1.1 × 106 (at α = 3 × 10−20, β = 3), we have physically desired results on the observational ground.

“…Anatomically, the vertebral arteries originate from the subclavian artery and the posterior inferior cerebellar artery (PICA) which provides arterial supply to the medulla and the suboccipital aspect of the cerebellum. Hence, the neurologic manifestation of Wallenberg’s syndrome is secondary to damage in the lateral segment of the medulla posterior to the inferior olivary nucleus, with atherosclerotic occlusion of the vertebral artery accounting for the most common cause, followed by the occlusion of the PICA, and the least common is the vertebral arteries [ 2 , 3 ]. Posterior ischemic strokes account for 20% of all ischemic strokes.…”

“…Posterior ischemic strokes account for 20% of all ischemic strokes. Hypertension, diabetes, and smoking are high-risk factors associated with the development of Wallenberg’s syndrome due to their role in atherosclerosis [ 2 - 4 ]. Wallenberg’s syndrome accounts for the bulk of posterior ischemic stroke syndromes, with men typically in their 60s mostly affected [ 2 , 3 ].…”

Wallenberg's syndrome, also known as posterior inferior cerebellar artery syndrome (lateral medullary syndrome), is known to be a common cause of posterior ischemic stroke syndromes in men in their 60s and may present with varied symptoms devoid of focal neurological signs making it easily missed as a differential of posterior ischemic strokes. It involves a stroke in the vertebral or posterior inferior cerebellar artery of the brainstem. In this case report, we critically examine the case of a 66-year-old man with newly diagnosed diabetes whose main presentation was dysphagia and unsteady gait. There was no motor or sensory examination finding in our patient, and the initial computed tomography of the brain was negative for any intracranial pathology leading to very low suspicion of stroke. However, given a high index of suspicion and a thorough oropharyngeal examination ruling out structural abnormality, magnetic resonance imaging of the brain revealed features suggestive of Wallenberg's syndrome. This case emphasizes careful consideration of posterior stroke syndrome when evaluating patients presenting with dysphagia without typical motor/sensory symptoms of cerebrovascular accident and the requirement of further imaging to support the diagnosis.
