Review Case Reports
Atypical Intracranial Meningioma with Metastasis to C-7 Vertebral Body: A Case Report.
Extracranial metastasis, mainly a feature of World Health Organization (WHO) grade III meningiomas, is only rarely reported in grade II meningiomas. ⋯ This case represents a rare instance of intraosseous spine as the first site of metastasis of WHO grade II atypical meningioma and is the first reported case of extracranial metastasis of a meningioma to the C7 vertebral body.

Retromedullary Hemangioblastoma Mimicking a PICA Aneurysm: Case Report & Literature Review.
Hemangioblastomas (HBMs) are benign vascular neoplasms that most commonly arise within the cerebellum. Although other vascular lesions should be considered in the differential diagnosis, HBMs rarely resemble aneurysms on neuroimaging and only 1 case of a cerebellar HBM mimicking a posterior fossa aneurysm has been reported. Here we describe a retromedullary HBM that masqueraded as a distal posterior inferior cerebellar artery (PICA) medullary branch aneurysm. ⋯ To our knowledge, this is the second case of HBM mimicking a PICA aneurysm. Given the rarity of PICA medullary branch aneurysms and their highly symptomatic nature, other etiologies, especially HBM, should be strongly considered when an apparent distal PICA aneurysm is diagnosed in an asymptomatic patient. If the lesion is unamenable to endovascular treatment, there should be high suspicion for HBM and subsequent craniotomy should be pursued.

Review Case Reports
Dengue Fever Presenting With Cervicodorsal Acute Spinal Spontaneous Subdural Hematoma-Case Report And Review Of Literature.
Neurologic complications are increasingly being reported in dengue epidemics. Intraspinal hematomas are rare, and those associated with dengue fever are still rarer with only 1 being reported in the literature. ⋯ Acute spontaneous spinal subdural hematoma (SSDH) is extremely rare but should be kept in mind in patients with dengue hemorrhagic fever. The radiologic findings could be deceptive and plain computed tomography and magnetic resonance imaging should be used as complementary studies to establish the diagnosis of acute spontaneous SSDH. The outcomes of SSDH are guarded, and elaborate patient counseling should be done preoperatively, keeping these in perspective.

Randomized Controlled Trial Comparative Study
Eleven-year follow-up of two cohorts of patients comparing stand-alone porous-tantalum cage versus autologous bone graft and plating in anterior cervical fusions.
Anterior cervical discectomy and fusion with a porous tantalum cage is an accepted method to treat degenerated cervical discs, with good results, similar to those with autologous bone graft and plating at short- and mid-term follow-up. However, to date, long-term follow-up studies have been performed. ⋯ These results show that the clinical and radiological outcomes achieved at mid-term follow-up using a tantalum cage for single-level anterior cervical discectomy and fusion will be maintained for 11 years postoperatively, similar to the results with autologous bone graft and plating.

Review Case Reports
Trigeminocardiac Reflex: Case Report and Literature Review of Intraoperative Asystole in Response to Manipulation of the Temporalis Muscle.
The trigeminocardiac reflex is a sudden onset of bradycardia, hypotension, apnea, or gastric hypermotility in response to stimulation of the trigeminal nerve. ⋯ Our report describes an unusual and extreme example of the trigeminocardiac reflex and explores possible etiologies. This is the third reported surgical case in which manipulation of the temporalis muscle alone was sufficient to elicit bradycardia and asystole, and the first such case within the context of neurosurgery. We emphasize the importance of surgical teams to be cognizant of such extreme examples of this reflex.
