Seeding metastases of a benign intraventricular meningioma along the surgical track is rare. We report a patient with a benign fibroblastic intraventricular meningioma that had spread along the path of previous surgery; the recurrences as well as the primary tumor were benign.

Randomized Controlled Trial Comparative Study
Cerebral oxygen metabolism and neuroelectrophysiology in a clinical study of severe brain injury and mild hypothermia.
Mild hypothermia has an important role in the treatment of severe brain injury and there are therapeutic windows for this technique for patients with severe brain injury. We used a randomized, controlled, clinical study to investigate indexes of cerebral oxygen metabolism and neuroelectrophysiology to evaluate the efficacy of mild hypothermia treatment in severe brain injury. A total of 148 patients (106 males and 42 females), aged 18 to 64 years with acute severe brain injury were selected from June 1998 to June 2004 from the Department of Neurosurgery at The First Affiliated Hospital of Chongqing Medical University. ⋯ For patients with GCS 3-4, there was no difference between the hypothermia and normothermia subgroups. We conclude that hypothermia had a significant therapeutic effect on severe brain injury of patients with GCS 7-8, had no effect on patients with GCS 3-4, and an uncertain effect on patients with GCS 5-6. The indexes of cerebral oxygen metabolism and neuroelectrophysiology indicated primary and secondary brain injury, respectively, and provided an effective way to evaluate brain injury.
