A Case of Opalski s Syndrome

Opalski’s syndrome is a variant of lateral medullary syndrome with ipisilateral hemiplegia that was first reported by Opalski. The lesion causing this syndrome is located lower than in Wallenberg’s syndrome and involves the corticospinal fibers caudal to the pyramidal decussation. A 46-yearold man with hypertension was admitted complaining of the sudden onset of vertigo, headache and gait disturbance. On admission, examination revealed monoparesis of the right lower limb, right Homer s syndrome, horizontal torsional nystagmus by lateral gaze, and decreased pain and temperature sensation of the his right face and left limbs. Diffusion-weighted imaging (DWI) showed an acute small infarct located on the right side of the lateral lower medulla. This is the first report of Opalski’s syndrome with lower medullary infarction detected by DWI in Korea.
