To the Editor:Bilateral medial medullary infarction(MMI)is a rare stroke subtype.[1]usually leads to quadriplegia,sensory disturbance,hypoglossal palsy,bulbar paralysis,etc.[2]We encountered a patient with rapidly progressive tetraparesis and diffusion-weighted imaging(DWI)exhibited a“heart appearance”sign in the bilateral ventral medulla.Computed tomography angiography(CTA)demonstrated that the left vertebral artery(VA)was hypoplastic and there was an atherosclerotic stenosis in the V4 segment.
