title: Dermatomal sensory manifestations in lateral medullary infarction.
abstract: A 61-year-old man who experienced a sudden onset of unstable gait followed by nuchal pain was admitted to our department. The neurologic examination revealed right-sided limb ataxia, right partial ptosis, and decreased sensation to 50% of the normal side to pinprick and temperature stimuli on the left side below the level of the T-6 dermatome. A lateral medullary infarction caused by spontaneous vertebral artery dissection was diagnosed by magnetic resonance imaging and computed tomography angiography. In conclusion, lateral medullary infarction is an important entity to consider in the differential diagnosis of dermatomal sensory manifestations.
