Scalp Cirsoid Aneurysm: An Updated Systematic Literature Review and an Illustrative Case Report.
Scalp cirsoid aneurysm is an arteriovenous fistula of the scalp that is unconnected by intracranial or cerebral vessels. Variceal dilatation of draining veins can produce cosmetic concerns, masses, local pain, palpable thrills, and audible bruits, headache, tinnitus, and hemorrhage. Its etiopathogenesis is not well understood. ⋯ An updated systematic review of the last 10 years publications was performed. Also, we report an illustrative case of a young boy with posttraumatic cirsoid aneurysm and good documentation on head vascular examinations, treated by multiple routes (percutaneous embolization with coils and endovascular embolization with cyanoacrylate) with a decrease of the pulsatile mass. A plastic surgery team performed gross total resection, and the final esthetic result was extremely satisfactory.

Review Case Reports
Transient Cortical Blindness Associated with Endovascular Procedures for Intracranial Aneurysms.
We presented 3 cases of transient cortical blindness secondary to contrast medium toxicity after endovascular procedures for intracranial aneurysms. We also reviewed the literature and found 12 cases of contrast-induced cortical blindness after endovascular procedures for intracranial aneurysms. ⋯ Based on our experience and the literature reports, we advocate corticosteroid and intravenous hydration for patients with contrast-induced cortical blindness after endovascular procedures for intracranial aneurysms.

Review Historical Article
The surgeon in action: representations of neurosurgery in movies from the frères lumière to today.
In this review, we examine the portrayal of neurosurgery and neurosurgeons in 61 movies produced from the beginnings of cinema from the Lumière brothers (1895) to 2017, across 4 continents and covering 10 cinematic genres. We find that these movies tend to shape most beliefs and stereotypes about neurosurgery. However, we notice that there is a trend to describe neurosurgery and neurosurgical disorders with more accuracy as we progress in time. Although it is not for the medical profession to dictate or censor fictional content, a keen eye on these depictions will help us to understand, and perhaps combat, some of the stereotypes and myths that continue to surround neurosurgery in the twenty-first century.

Hemorrhagic meningiomas, although relatively uncommon, represent a distinct clinical entity. In some cases, these meningiomas can closely mimic a thrombosed aneurysm. We present a case of a jugular tubercle meningioma whose radiographic and clinical picture initially suggested a ruptured, thrombosed vertebrobasilar aneurysm. This case serves to highlight several key differences between these 2 pathologies that can assist in diagnosis. ⋯ Hemorrhagic meningiomas can have a clinical and radiologic picture that closely resembles a ruptured, thrombosed cerebral aneurysm. Based on our single case, we suggest several important diagnostic differentiators between these 2 entities. We found the hemorrhagic meningioma to exhibit eggshell-like rim calcification, thick, irregular peripheral enhancement, and a central cystic component. This can be contrasted to the classic appearance of a thrombosed aneurysm with mixed T1-, T2-weighted signal intensity, and occasional regular, thin peripheral enhancement.

Meningioma, a common primary brain tumor in adults, is graded based on World Health Organization criteria that rely on histology alone. This approach is unable to determine conclusively which tumors, especially benign or atypical, will recur. ⋯ Immunotherapy is also being trialed in treating high-grade and recurrent meningioma. This review summarizes recent developments characterizing meningioma using genetic and immunologic biomarkers and how these molecular tools may be integrated into existing care together with current World Health Organization grading to improve diagnosis, prognosis, and therapy.
