Approximately 60% of meningiomas are associated with peritumoral edema. Various causative factors have been discussed in the literature. The objective of this study was to investigate the correlation of PTBE with clinical, radiologic, and surgical aspects and recurrence of meningiomas. ⋯ Peritumoral brain edema may be related to the invading potential of meningiomas and may play a role in the recurrence potential of the tumor. As a consequence, it is reasonable to consider the presence of edema as an additional factor to be taken into account when mapping out strategies for the treatment of meningiomas.

The aim of this study was to determine the ideal point for a ventricular puncture in pterional craniotomies. ⋯ An intraoperative ventriculostomy can be performed safely and reliably using the new landmark 2.5 cm superior to the lateral orbital roof and 4.5 cm anterior to the sylvian fissure in aneurysm surgery using a pterional craniotomy.

Comparative Study
Neuroprotective effect of erythropoietin after experimental cold injury-induced vasogenic brain edema in rats.
The aims of this study were to evaluate the efficiency of EPO in the treatment of cold injury-induced brain edema, apoptosis, and inflammation and to compare its effectiveness with DSP. ⋯ Erythropoietin and DSP were found to be neuroprotective in cold injury-induced brain edema model in rats via anti-apoptotic and anti-inflammatory actions.
