Opalski syndrome, a rare variant of wallenberg syndrome, the first case reported from Pakistan: A case report

Background: Wallenberg syndrome, also known as a lateral medullary syndrome, is a rare neurological condition caused by an infarction in the brainstem's lateral medulla. There are subtypes of Wallenberg syndrome with distinctive and atypical symptoms, such as Opalski syndrome. Case presentation: A 41-year-old hypertensive male arrived at the emergency department with abrupt onset of right-sided bodily weakness, vertigo, facial numbness, dysphagia, hoarseness of voice, and double vision. The neurological examination indicated right hemiparesis, right facial numbness, crossed sensory deficit, right limb ataxia, right uvulopalatal deviation, and vertical double vision. An MRI showed a lateral medullary infarct leading to the suspicion of the atypical lateral medullary syndrome. The patient was treated with physiotherapy and daily oral medications including aspirin, clopidogrel, atorvastatin, and Cap Risek. On follow-up 14 days later, the patient's condition had significantly improved. Conclusion: This case study demonstrates the significance of recognizing atypical variants of Wallenberg syndrome, such as Opalski syndrome, in order to provide a correct diagnosis and the most effective treatment. Our patient's condition improved as a result of the therapy measures used, however, people with Opalski syndrome may have a poor prognosis and require continuous monitoring.
