Summary table for Bilateral Medial Medullary Infarction

Etiology	The etiological classifications of infarctions are large-artery atherosclerosis (LA), small-vessel disease (SV), arterial dissection (DI), cardiac embolism (CE), and stroke of un- determined etiology.
Incidence	Medial medullary infarction (MMI) is a rare stroke subtype, accounting for only 0.5—1.5% of all strokes [1.2], and bilateral MMI is even rarer [3].
Risk factors	Atrial fibrillation, hypertension, smoking habits, diabetes mellitus, ischemic heart disease, and dyslipidemia
Treatment	The same as cerebral infarction treatment, and to perform endotracheal intubation when respiratory distress occurs.
Symptoms	They include quadriplegia, dysarthria, hypoglossal palsy, respiratory failure, and so on.
prognosis	The clinical outcome of bilateral MMI is usually poor [6].
Imaging findings	Brain magnetic resonance imaging (MRI) shows a hyperintense “heart appearance” signal in the bilateral anteromedial medullae.
