Abstract
Objective To Investigate the clinical and imaging features of bilateral medial medullary infarction ( BMMI) .Methods The clinical data of 20 BMMI patients were analyzed retrospectively.Results In 20 cases, the initial symptom was dizzy in 6 cases ( 30%) , quadriplegia in 6 cases ( 30%) , hemiplegic paralysis in 4 cases (20%), dysphagia in 3 cases (15%), weakness of lower limbs in 1 cases (5%).All 20 cases were acute onset, progressive in 16 cases.The main clinical features were shown that 20 cases demonstrated quadriplegia, 17 cases dysphagia, 15 cases dysarthria, 13 cases vertigo, 11 cases tongue atrophy, 7 cases horizontal nystagmus, 8 cases difficulty breathing, 8 cases deep sensory disturbance, 16 cases bilateral babinski sign positive.Twenty cases of brain MRI show bilateral medial medullary infarction, DWI found increased signal intensity in double inside of the medulla oblongata in 18 cases, MRI T1 showed decreased signal and T2 showed increased signal in double inside of the mudullary infarction in 10 cases.MRA, CTA and DSA showed hemadostenosis and vascular occlusion in the vertebral artery in 8 cases.Seven cases were benign after treatment and could walk independly.Conclusions The clinical manifestation of BMMI are quadriplegia on acute onset, and bilateral synmetry, bilateral pyramid sign, impaired vagus nerve, hypoglossal nerve and deep feeling.Brain MRI with DWI examination is helpful for early diagnosis, and most patients with active treatment could get good prognosis.关键词
