Generally accepted method of diagnosis of vertebral arteries dissection is considered MRI, but an experienced sonographer may suggest the diagnosis of dissection on the basis of the characteristic features 1,2. Intravascular echoes are non-specific findings of dissection, but the expansion of the arterial lumen in one section and the normal diameter of the other section in conjunction with intravascular echo making it a more certain diagnosis. In this case, MRI was used to verify the diagnosis, which showed intramural hematoma on T1 fat saturated sequences.
