Patterns of Lateral Medullary Infarction

Lateral and Medial Medullary Infarction

Background and Purpose—No large-scale study has ever compared the clinical and radiological features of lateral medullary infarction (LMI) and medial medullary infarction (MMI). The aim of this study was to investigate them through the use of cooperatively collected cases. Methods—Medical information on all patients from 1996 to 2000 with medullary infarction (MI) proven by brain MR images at 3...

Impaired Sacculocollic Reflex in Lateral Medullary Infarction

OBJECTIVE The aim of this study was to determine saccular dysfunction by measuring cervical vestibular-evoked myogenic potentials (cVEMP) and to correlate abnormality of cVEMP with results of other vestibular function tests in lateral medullary infarction (LMI). METHODS We recorded cVEMP in 21 patients with LMI documented on MRI. cVEMP was induced by a short tone burst and was recorded in con...

Lateral medullary infarction presenting contralateral palatal paresis.

Palatopharyngeal paresis has never been reported to be contralateral in the lateral medullary infarction (LMI). A 65-year-old lady with acute dorsolateral infarction in the left medulla presented mild hoarseness, mild dysphagia, mild gait ataxia along with marked hypalgesia and thermal anesthesia on the right limbs. To our surprise, palatal weakness was on the right side, instead of being on th...

Patterns of lateral medullary infarction: vascular lesion-magnetic resonance imaging correlation of 34 cases.

BACKGROUND AND PURPOSE Correlation of MRI findings with various vascular pathologies has rarely been attempted in patients with lateral medullary infarction (LMI). The aim of the present study was to correlate the diverse MRI lesions with the vascular lesions seen on conventional cerebral angiography in LMI. METHODS The subjects included 34 patients with LMI who underwent both MRI and convent...
