Case Discussion
Typical presentation and CT findings of a hyperacute, left-sided MCA infarction.
The hyperdense MCA sign is the earliest CT sign of an MCA infarction, due to hyperattenuating thrombus in the arterial lumen. Specificity of this sign is high, however it is present only in a minority of cases.
