The DWI sequences showed restricted diffusion in bilateral paramedian thalami extending to the left rostral midbrain and a small analogous alteration in the left cerebellum; no alterations were visible in FLAIR sequences, and a diagnosis of hyperacute AOP infarction was made (Fig. 1). 120 min from symptom onset, intravenous thrombolysis was administered with prompt anisocoria regression.
