During the thrombolysis process, vital signs such as heart rate and blood pressure were monitored, and the NIHSS score was evaluated every 15 min (Figure 1).
The cranial MRI showed no abnormal signal was found in T1-weighted imaging, T1WI (TI), T2-weighted imaging, T2WI (T2), diffusion-weighted imaging (DWI) and susceptibility weighted imaging (SWI).

The cranial MRI and systemic vascular examination were arranged to find the cause of stroke, no abnormal signal was found in T1-weighted imaging, T1WI (T1), T2-weighted imaging, T2WI (T2), and diffusion-weighted imaging (DWI), and there was no microhemorrhage-related signal in susceptibility weighted imaging (SWI) (Figure 2).
CT angiography (CTA) of left atria-pulmonary vein showed the middle branch of the right pulmonary vein was variable.
