Quadriplegia or dysesthesia in all four limbs may be the initial symptom of bilateral medial medullary infarction (MMI), a very rare cerebrovascular accident with a dismal prognosis. Clinical diagnosis of bilateral MMI is still challenging and can be confirmed by diffusion-weighted (DW) magnetic resonance imaging (MRI) in the early stage. Here, we report the case of a 60-year-old male who presented to the emergency department complaining of numbness in all four limbs. DW-MRI was used to identify brain lesions 24 hours after the symptom onset. The infarct, on axial MRI sections, showed the characteristic 'airpod sign'/heartshaped appearance due to the morphology of the area involved in the medulla.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
