- Abstract
- Background
and Purpose : Medial medullary syndrome (MMS) is characterized clinically by a triad of ipsilateral hypoglossal nerve palsy, contralateral or ipsilateral hemiparesis sparing the face, and sensory disturbance of position and/or vibration. However, this syndrome is quite rare, and its clinical and radiological findings have not yet been clearly characterized.
Methods
: We reviewed 9 patients with AMS who were diagnosed based on their
clinical and magnetic resonance imaging (MRI) findings.
Results
: There were 8 men and I woman with average age of 60 (41 to 75) years.
The risk factors included hypertension in 8, DM in 6, cigarette smoking in 4,
hypercholesterolemia in 4, gout in I and atrial fibrillation with LV dysfunction in 1.
Their, clinical findings included contralateral hemiparesis in 9 and contralateral
hermhypesthesia in & Only one patient presented with ipsilateral lingual paresis. The
motor weakness was mild in 5 and moderate in 4. MRI results showed the lesions were
located in the upper medulla in 7 and lower medulla in 2. Alteration of vertebral artery
flow signal void in MRI was observed in 6 patients. Three patients had additional
infarcts in the lateral medullary area. Prognosis of the motor weakness was good in 5
and stationary in 4.
Conclusion
: Our patients generally presented with unilateral sensorimotor stroke.
Ipsilateral h6miparesis and tongue weakness, unique signs of @, were found only rarely,
and the absence of these findings often made it difficult to localize the lesion by clinical
judgement only.
