Comparative Study
Global Diversity and Academic Success of Foreign-Trained Academic Neurosurgeons in the United States.
To quantify the proportion of academic neurosurgeons practicing in the United States who acquired residency training outside of the United States and compare their training backgrounds and academic success with those who received their residency training in the United States. ⋯ A small group of U.S. academic neurosurgeons (6.3%) have acquired residency training outside of the United States, representing all major regions of the world. Their general demographic data and academic accomplishments are comparable to those of U.S.-trained neurosurgeons.

We report a case in which common radiologic images masked a rare case of supratentorial hemangioblastoma (HBL). Other peculiarities of this case are the clinical presentation with status epilepticus and the occurrence of a supratentorial HBL unrelated to von Hippel-Lindau syndrome. Based on clinical and radiologic findings, including massive cerebral edema and hemorrhagic presentation, our preoperative diagnosis was a cerebral metastasis. In this scenario, physicians must take into account the words of the Roman fabulist Phaedrus: "Non semper ea sunt, quae videntur, decipit frons prima multos" (things are not always what they seem; the first appearance deceives many).

Case Reports
Intracranial Blood Flow Changes in Patients with High-grade Severe Carotid Artery Stenosis after Stenting.
We investigated whether the cerebral hemodynamic changes of pre- and poststenting in patients with severe carotid stenosis differ by stenosis grades. ⋯ The improvement of brain perfusion combined with the normalization of collateral flow through the circle of Willis after CAS was observed only in patients with HGSS.

Prognostic factors for the disease course of patients with spondylodiscitis have not been well studied. ⋯ Compared with MRI, CT imaging parameters have a higher prognostic value regarding the disease course. Patients infected with low-virulence bacteria and atypical MRI findings are at higher risk for poor clinical outcome and thus warrant closer monitoring.

To evaluate pain control and side effects after gamma knife radiosurgery (GKRS) for classical idiopathic trigeminal neuralgia (TN) with or without neurovascular compression (NVC). ⋯ NVC is not a predictive factor for pain control after GKRS for the treatment of idiopathic TN. Side effects may occur more frequently in patients with NVC at the target coordinate when a root entry zone is used, but the subjective symptoms are not always bothersome.
