“…The study by Narayan et al [ 28 ], which was until now the largest series with 80 cases of GIMs, demonstrated that regression analysis showed age, sex, location of the tumor [ 44 , 45 ], Simpson grade of excision, and histology of tumor were the factors that significantly affected the KPS, complications, and recurrence [ 39 , 46 ]. Our series confirms just some of these findings whereas the mortality rate, recurrence rate, Simpson grade, and KPS are comparable between the two groups, but there is a higher rate of complications in the first 30 days after the surgical procedure for GIMs compared with smaller meningiomas [ 47 , 48 , 49 , 50 ]. We identified a higher incidence of postoperative ischemia, infections, and seizure in the GIM group.…”
