Case contributed by Dr Andrei Dumitrescu


Sudden onset aphasia and right side hemiparesis.

Patient Data

Age: 70 years
Gender: Male

Hyperdensity of the proximal MCA on the left side.
Slight hypodensity of the basal ganglia and white matter of the frontal, parietal and temporal lobes of the left hemisphere.

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.
