Expression of GLUT3 and HIF-1α in Meningiomas of Various Grades Correlated with Peritumoral Brain Edema

Figure 1

Types of peritumoral brain edema (PTBE) in meningiomas (black arrows). (a) No peritumoral edema around the meningioma, corresponding to PTBE grade 0. (b) Peritumoral edema (black arrow) around the tumor, but the edema range did not exceed 2 cm, corresponding to PTBE grade I. (c) Peritumoral edema (black arrow) around the tumor. The edema range is more than 2 cm but is limited to one half of the cerebral hemisphere, corresponding to PTBE grade II. (d) A wide peritumoral edema (black arrow) visible around the tumor, and the edema covers more than half of the cerebral hemisphere, corresponding to PTBE grade III.
