Meningiomas are the most common primary benign intracranial brain tumors (
1
). While the majority of meningiomas are classified World Health Organization (WHO)
grade 1 tumors, a minority is classified as grade 2 or 3 lesions, based on features
of cellular atypia and invasive growth (
2
). Surgical resection remains the treatment of choice for progressive, space-occupying
and/ or symptomatic lesions, especially in favourable locations such as convexity
meningiomas (
1
). While the aim of surgery is gross total resection (GTR), the extent of resection
depends on factors such as tumor location, size and involvement of critical tissue
(
1
). Gross total resection and subtotal resection (STR) are defined according to the
Simpson classification: Simpson grade I – III constitute gross total resection and
Simpson grades IV – V form the group of subtotal resection. (
