Page 328, Table 1.

The phrases “Mortality rate (cases with available data) (5/8)=62.5%” and “Overall mortality rate (cases with available data) (7/10) = 70.0%” of the Table 1 should read “Mortality rate (cases with available data) (3/8)=37.5%” and “Overall mortality rate (cases with available data) (5/10)=50.0%”, respectively.

The sentence “However, when considering the lethality of the high-grade-only subset, this value increases to 70% or even 100% in cases with an accompanying glioblastoma component (Table 1).^8-13” on page 328 should read “However, when considering the lethality in the sole high-grade subset, this value increases up to roughly 40% or even 100% in those instances with an accompanying glioblastoma component (Table 1).^8-13”

The sentence “As shown in our case and previously advised by other authors, gliofibroma prognosis is greatly influenced by the degree of anaplasia of the glial component” on page 329 should read “As shown in our case and previously advised by some authors, gliofibroma prognosis is, indeed, influenced by the degree of anaplasia of the glial component.”
