Review Case Reports
Concomitant Sacral Dural Arteriovenous Fistula and Conus Medullaris Arteriovenous Malformation with Respective Drainage Veins: Case Report and Literature Review.
Spinal dural arteriovenous fistulas (DAVFs) and spinal arteriovenous malformations (AVMs) are relatively rare. Moreover, multiple spinal cord vascular lesions in an individual, such as double DAVFs and DAVF with AVM, are extremely rare. To date, there are only several reported cases of concomitant spinal DAVFs and AVMs. ⋯ The concomitant presence of sacral DAVF and conus AVM is extremely rare. Nonetheless, clinicians should be aware of the possibility of the coexistence of multiple types of spinal vascular lesions in a single patient.

Review Case Reports
Surgically treated epilepsy due to developmental venous anomaly of the brain. Case report and review of the literature.
A congenital malformation of the brain vessels, developmental venous anomaly (DVA) is considered a benign lesion, requiring no intervention unless symptomatic. Epilepsy is a well-known clinical manifestation of DVA. Successful surgery for DVA-associated epilepsy with has been sporadically reported in the literature; however, in all published cases, the anomaly was left intact along with the accompanying lesion. Here we present a surgical case of DVA located in the vicinity of the motor cortex causing drug-resistant simple partial epilepsy. ⋯ DVA removal can be performed in selected cases, but more studies are needed to assess the complication rate.

Randomized Controlled Trial
Rate and Predictors of Unanticipated Surgical Evacuation in Patients with Intracerebral Hemorrhage: Post Hoc Analysis of ATACH 2 Trial.
We performed this analysis to identify the rates, predictors, and associated outcomes of unexpected neurosurgical evacuation in a multicenter randomized clinical trial, Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH) 2. ⋯ In the large cohort of ATACH 2 subjects with good grade ICH, the rates of unanticipated surgical evacuation were low and were associated with relatively high rates of death or disability at 3 months.

The analysis of perioperative electronic patient portal (EPP) communication may provide risk stratification and insight for complication prevention in patients with affective disorders (ADs). We aimed to understand how patterns of EPP communication in patients with AD relate to preoperative narcotic use, surgical outcomes, and readmission rates. ⋯ AD patients have specific patterns of perioperative EPP communication. They are at a higher risk of postoperative complications. Addressing these concerns early may prevent more serious morbidity and avoid unnecessary ED visits and readmissions, thus reducing costs and improving patient care.

Review
Diffusion and perfusion weighted magnetic resonance imaging methods in non-enhancing gliomas.
Routine diagnostic magnetic resonance imaging (MRI) uses enhancement of the tumor tissue as a marker of malignancy in intracranial gliomas. However, several high-grade tumors do not exhibit enhancement, and, conversely, some low-grade gliomas do demonstrate enhancement. ⋯ These advanced MRI methods include diffusion-weighted imaging, diffusion tensor imaging, diffusion kurtosis imaging, arterial spin labeling imaging, dynamic susceptibility contrast imaging, and dynamic contrast-enhanced imaging. This review focuses on the utility of these methods for better characterization and grading of nonenhancing gliomas, as it is more difficult to accurately devise an optimal treatment strategy for these tumors compared with enhancing gliomas.
