Brain MRI findings. First episode: Images (A-E); second episodes (F-J) (resembling residual findings on further follow up MRIs): (A+F): T2-weighted-images (T2W); (B+G): fluid-attenuated inversion recovery (FLAIR) images; (C+H): diffusion-weighted images (DWI); (D+I): apparent diffusion coefficient (ADC) images; (E+J): T1-weighted images (T1W) with gadolinium (Gd). Images show left-dominant cerebellar hyperintense lesions on T2W, FLAIR, and ADC images that are hypointense without Gd enhancement T1W images. DWI images at first episode showed hyperintense lesion and were normal at second episode.

Brain MRI was repeated revealing bilateral cerebellar edema that was interpreted as subacute stroke leading to a stroke work-up including transthoracic echocardiography, trans- and extracranial Doppler ultrasound and long-term ECG without pathological findings (Figure 1, Table 2).
