Findings:

Initial CT demonstrates verty subtle loss of the anterior insular cortex and blurring between the lentiform nuclei and external capsule, which was thought to possibly represent edema from early ischemic changes.

Follow up CT 2 days later demonstrated a focal area of decreased density involving the left basal ganglia and extending into the subcortical white matter of the left insula compatible with progression from the prior study. The area of hypodensity measures
approximately 2.5 cm x 3.0 cm.

Diagnosis: Acute ischemic infarct involving the left basal ganglia and left insula.
