Abstract
Lateral Medullary Syndrome (LMS) is a well-documented vascular syndrome of the posterior circulation territory. This syndrome is easily localized because of characteristic presentation, unique territory of blood supply and very small area of involvement. We present a case of Wallenberg's syndrome which did not have all the classical components of the syndrome, like Horner's syndrome. It was diagnosed as Opalski syndrome, which is a rare variant of Wallenberg syndrome, where lateral medullary syndrome is associated with ipsilateral hemiparesis. This case report highlights how differential involvement of the lateral part of medulla can result in varied presentation.
