Abstract: Objective To investigate the clinical and imaging characteristics of bilateral medial medullary infarction. Methods The clinical data of 3 patients with bilateral medial medullary infarction admitted to Shengjing Hospital of China Medical University were analyzed retrospectively. The related literature was reviewed. Results Three patients in this group were all males. Their main clinical manifestations were quadriplegia, dysarthria, and paresthesia, and 1 of them complicated with respiratory failure. One patient was suspected of having Guillain-Barre syndrome. The hyperintensities of heart-shape,Y- shape,and V- shape were its imaging features of typical MRI diffusion weighted imaging. Conclusion Bilateral medial medullary infarction is a rare posterior circulation ischemic lesion in clinical practice. Its early symptoms are not typical and easy to be misdiagnosed and missed. MRI diffusion weighted imaging is its main imaging examination method.
