Dorsal Medullary Infarction

Medial Medullary Infarction

Background and Purpose—Clinical-imaging correlation and long-term clinical outcomes remain to be investigated in medial medullary infarction (MMI). Methods—We studied clinical, MRI, and angiographic data of 86 consecutive MMI patients. The lesions were correlated with clinical findings, and long-term outcomes, divided into mild and severe (modified Rankin scale 3), were assessed by telephone in...

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...

Magnetic resonance imaging of medial medullary infarction.

Medial medullary infarction is characterized by ipsilateral hypoglossal nerve palsy, contralateral hemiparesis sparing the face, and contralateral disturbance of deep sensation. Although it is possible to make a clinical diagnosis in typical patients, diagnosis is difficult if hypoglossal nerve palsy is absent. We describe a patient with medial medullary infarction without hypoglossal nerve pal...
