Figure 3.

A 86 year old female patient presenting within 90 min of symptom onset. (A) Unenhanced CT demonstrates right thalamic and internal capsule hematoma with associated third ventricle mass effect. (B) A small focus of enhancement consistent with the Spot Sign is seen on the CTA raw image. (C) Post-contrast CT performed immediately following the CTA shows increase in contrast density from the CTA consistent with active contrast extravasation. (D) Unenhanced follow up CT at 6 h demonstrates early hematoma expansion. A trace of intraventricular hemorrhage is present within the right trigone.
