Review Case Reports
Subfrontal Schwannoma: Case report and review of literature.
Although attributing the origin of schwannomas from the olfactory nerve is nearly impossible, if they do not have Schwann cells, intracranial supratentorial schwannomas are mainly located in the anterior skull base. ⋯ We describe this case in detail and discuss the likely origin of this tumor, with a concomitant literature review.

Randomized Controlled Trial Multicenter Study Observational Study
The Outcome of Severe Traumatic Brain Injury in Latin America.
Traumatic brain injury (TBI) disproportionately affects lower- and middle-income countries (LMIC). The factors influencing outcomes in LMIC have not been examined as rigorously as in higher-income countries. ⋯ Mortality from severe TBI is high in Latin American LMIC, although the rate of favorable recovery is similar to that of high-income countries. Demographic factors such as race and study site played an outsized role in predicting outcome; further research is required to understand these associations.

Congenital Absence of the Posterior Element of C1, C2, and C3 Along with Bilateral Absence of C4 Pedicles: Case Report and Review of the Literature.
Abnormalities of the posterior arch of vertebrae are rare conditions that may incidentally be found on neck radiographs. We report a case and present a comprehensive review of the literature. ⋯ The diagnosis of posterior arch abnormalities is of high-level of importance because of resultant neurologic defects. To the best of our knowledge, no case of this type has been reported in literature thus far.

Angiographic "Blush" After Stereotactic Radiosurgery Ablation of Residual Arteriovenous Malformation in Pediatric Patient: Case Report and Review of Literature.
While surgical resection remains a primary treatment for accessible arteriovenous malformations (AVMs), stereotactic radiosurgery (SRS) has become thoroughly integrated into the AVM armamentarium; however, delayed sequelae of this treatment have become evident with increased long-term follow-up. To our knowledge, this is the second case of an aberrant local arterial angiographic blush without early venous drainage or an associated lesion following AVM SRS. ⋯ Although there is a paucity of information on angiographic blush following AVM SRS, consensus in the literature suggests that without early venous drainage, these lesions appear to pose an insignificant threat to the patient. These angiographic findings may be on a spectrum of delayed cerebrovascular radiation changes, and thus indefinite follow-up may be considered, especially in pediatric patients.

Review Case Reports
Endovascular Management of Multiple Dysplastic Aneurysms in a Young Man with an Unknown Underlying Cause: A Case Report and Review of the Literature.
Intracranial aneurysms are the leading cause of nontraumatic subarachnoid hemorrhage and are most commonly associated with the anterior cerebral artery (ACA) and anterior communicating artery complex. We describe the presentation and management of a 27-year-old man with concurrent bilateral A1-2 junction aneurysms and fusiform intraorbital ophthalmic artery (OA) aneurysms. ⋯ We report the case of a young man with no past medical history who presented with multiple dysplastic aneurysms. Successful staged endovascular intervention resulted in obliteration of aneurysms with spontaneous obliteration of the intraorbital OA aneurysms observed at 3 months. We present this case to review the multiple challenges of managing complex ACA aneurysms and to highlight the usefulness of endovascular intervention in their treatment.
