A probable cavernoma in the medulla oblongata presenting as Opalski syndrome: A rare entity

Abstract

In 1949, Opalski described the findings of two patients with lateral medullary infarcts who had mild hemiparesis with hyperreflexia and Babinski's sign, along with features of LMS. [...]patients with LMS who have ipsilateral hemiparesis, hyperreflexia, and Babinski's sign are stated to have Opalski syndrome. [...]it may occur due to the involvement of medullary penetrating arteries arising from anterior spinal artery or distal vertebral artery that supply the pyramidal fibers distal to the decussation.
