MCA Superior Division Infarction - Case 1

A 87 year old man with atrial fibrillation was found with a left hemiparesis, affecting the arm and lower face more than the leg, and a right gaze preference.

               Note the "Hyperdense" MCA Sign                                                                    Outline the Infarction                                    

Axial CT scan - 3 days later. The CT shows hypodensity mainly affecting the superior division of the right middle cerebral artery, involving the right frontal lobe above the sylvian fissure. This is one of the most common locations for embolic stroke, either from a proximal arterial source or from the heart.
