On follow-up after 10 days, the patient developed left-sided hemiparesis and confusion. Non-contrast CT (a, b) shows multiple infarcts involving the right lentiform nucleus (asterisk in a) and right frontal periventricular white matter (asterisk in b). MIP (c) and volume rendering (d) images of CTA show severe vasospasm of the right MCA segments M1 and M2 (arrows in c and d) as well as the right ACA segment A1. CT perfusion maps show significant perfusion deficit at the right side; reduced CBV (e), reduced CBF (f), prolonged MTT (g), and prolonged TTP (h)
