Review Case Reports
Hypertrophic Olivary Degeneration and Holmes' Tremor: Case Report and Review of the Literature.
Hypertrophic olivary degeneration (HOD) is very rare type of degeneration that causes hypertrophy rather than atrophy. The classical presentation of HOD is palatal myoclonus. However, HOD may rarely present with Holmes tremor (HT). HT is unusual symptomatic tremor characterized by combination of rest and intention tremor. It has been reported in small case series, so far. ⋯ Although pontine-midbrain hemorrhage may cause HT in the late period, HOD can be revealed on magnetic resonance imaging. Tract anatomy, especially the Guillain-Mollaret triangle, should be considered to explain the relationship between HT and HOD.

Review Meta Analysis
Prognostic value of abnormal muscle response during microvascular decompression for hemifacial spasm: a meta-analysis.
To perform a comprehensive meta-analysis to systematically assess the value of abnormal muscle response (AMR) in predicting the surgical outcome of patients with hemifacial spasm. ⋯ The disappearance of AMR during microvascular decompression demonstrates limited prognostic value for a favorable short-term outcome, and does not appear effective in predicting the long-term outcome of patients with hemifacial spasm.

Central neurocytomas (CNCs) are rare intraventricular lesions comprising <1% of primary brain tumors. Their surgical and adjuvant management is unclear. ⋯ RT remains an important adjuvant treatment that can improve patient survival in the presence of MSR to levels comparable to those of GTR or GTR + RT. Where total resection carries too much risk, MSR + RT can be considered as the next best alternative for tumor control.

Review Historical Article
Extensive pneumocephalus caused by multidrug-resistant Klebsiella pneumoniae.
The practice of surgical intervention for the treatment of psychiatric disorders has a rich and fascinating history. Arguably dating back to more than 7 millennia ago, neurosurgery for psychiatric disease is shrouded in stigma, being widely portrayed in the media (almost invariably negatively). ⋯ The landscape of neurosurgery for psychiatric conditions has shifted constantly since, guided by new developments in neuroscience and surgical technology. In this article, we outline the salient events in the story of this field.

Cavernous sinus dural arteriovenous fistulas (CS dAVFs) occasionally behave aggressively (e.g., intracranial hemorrhage, venous infarction, seizures) depending on the drainage flow and presence of a collateral route of cortical or basal cerebral venous drainage. When a CS dAVF with aggressive behavior is encountered, a radical cure is required to avoid catastrophic deficits. However, conventional transvenous cavernous sinus (CS) embolization via the inferior petrosal sinus does not always achieve shunt obliteration. We herein report a case of surgical venous drainage disconnection in an 83-year-old woman with a CS dAVF. ⋯ Surgical venous drainage disconnection from the fistulous point may be an alternative radical therapy for CS dAVFs with aggressive behaviors.
