To compare clinical outcomes and payments between glioma resections with and without functional mapping. ⋯ Intraoperative functional mapping during glioma resection was associated with decreased complications, reoperations, emergency department visits, and shorter lengths of stay. Furthermore, total charges of mapped resections were not significantly different from those of conventional resections. These findings support the usefulness of functional mapping for resection of supratentorial primary malignant gliomas.

Case Reports
Symptomatic recurrence of cervical spine myelomeningocele in an adult patient - Case report.
Cervical myelomeningocele (MMC) is a very rare neural type defect that is usually discovered and managed in childhood. It is best described as a closed type of spinal dysraphism, where the posterior portion of the cervical thecal sac forms a pouch that bulges out through a narrow posterior spina bifida and contains spinal neural tissue with or without cerebrospinal fluid. ⋯ Cervical MMC is extremely rare in adults, the symptomatic progression of which is most likely because of cord tethering by fibrotic tissue formation over years. Early surgical correction and release of the tethered cord is relatively safe and prevents the evolution of neurological symptoms.

Case Reports
Cavernous-Carotid Fistula Presenting with Intracerebral Hemorrhage in the Absence of Ocular Symptoms: a case report.
Cavernous-carotid fistulas (CCFs) can present with a variety of symptoms depending on the anatomy of the fistula and its venous drainage. Patients most commonly present with scleral injection, pulsatile exophthalmos, and/or chemosis. ⋯ The morphology of the venous drainage can lead to atypical hemorrhagic presentation, whereas dilatation of one of the tributary veins with cortical venous reflux should warn the interventionist the path the embolysate may follow. We provide our experience with this unique presentation and its treatment.

Seven-Tesla (7T) magnetic resonance imaging (MRI) has demonstrated value for evaluating a variety of intracranial diseases. However, its utility in trigeminal neuralgia has received limited attention. The authors of the present study applied ultra-high field multimodal MRI to two representative patients with secondary trigeminal neuralgia due to epidermoid tumors to illustrate the possible clinical and surgical advantages of 7T compared with standard clinical strength imaging. Techniques included co-registration of multiple 7T sequences to optimize the detection of potential concurrent neurovascular and neoplasm-derived compression. ⋯ 7T provided superior visualization of vital landmarks and subtle nerve and vessel features. Co-registration of various advanced 7T modalities may help to resolve complex disease etiologies. Future studies should explore the extent to which this dual etiology might persist across tumor types and utilize diffusion-based techniques to quantify what microstructural differences might exist between patients with trigeminal neuralgia from varying etiologies.
