Patchy hypodensity in the white matter of the middle cerebral artery territory is noted. There is also positive mass effect in the region with loss of grey-white matter differentiation and probable cortical swelling.
In the Sylvian fissure, a branching calcific density is present consistent with a calcified embolus, with the largest component extending into the inferior division of the MCA. Features are those of a subacute infarct secondary to a calcified thromboembolism.
