CT scan on Day 0 shows subarachnoid hemorrhage with intraventricular and intraparenchymal hemorrhage. CT angio on day 0 showed right middle cerebral artery aneurysm. On day 4 and 10, CT scan showed resolving hematoma without hydrocephalus. On day 13, an infarct was seen in the right basal ganglia with resolving hematoma. On day 16 and 20, bilateral infarcts were seen in both the basal ganglia and internal capsule.

CT-Angiogram demonstrated a right middle cerebral artery (MCA) bifurcation aneurysm [Figure 1]. Serial CT scans done in the post-operative period [Figure 1] showed gradual resolution of the intracerebral and intraventricular blood. Serial CT scans over this period [Figure 1] showed well defined infarcts developing in both internal capsules and right thalamus without any infarct in major vessel territory, suggesting no major vessel spasm.
