Clinical-MRI correlation study of medullary infarction

Objective To investigate the relation between lesions of medullary infarction and clinical symptoms and signs.Methods Eleven patients with medullary infarction confirmed by MRI were identified.Their clinical presentations and the relation between clinical presentation and location of lesion in MRI were assessed and analyzed.Results Among the 11 patients,5 cases suffered from lateral medullary infarction,6 medial medullary infarction(including two cases of bilateral infarction).Regarding clinical symptoms,common symptoms in lateral medullary infarction are blurred speech,dizziness,choking water,swallowing difficulties and facial numbness;in medial medullary infarction are limb weakness and blurred speech.The common signs of lateral medullary infarction are dysarthria,sensory disturbance,Horner sign and facial paralysis;in medial medullary infarction are paralysis of limbs and peripheral paralysis of the tongue.Conclusion Clinical manifestations are vailed depending on the sites of medullary infarction.MRI is helpful in diagnosing of medullary infarction.
