^aThose reports that lack particular data or details are denoted as “unspecified” and are subtracted from the total number of patients (the denominator) when calculating percentages. There were two case reports that contained multiple MA lesions that affected both right and left hemispheres and, therefore, were not included in calculating percentages for side of involvement. Number of patients included in calculating percentages in each subset is denoted by (𝑛).
