Life and death in Italian prehistory: the case of the sailor from Spina.
There are few reported cases in the literature of spinal injuries from the past, and all of them resulted in the death of the individual or led to severe health consequences. From the historical record, it is well known there were no cures or treatments for spinal lesions in the past. Given the paucity of historical documents focused on this topic, anthropological research on spinal injuries can contribute with important information regarding the medical history of this kind of trauma. Moreover, skeletal trauma and occupational markers may be crucial for the reconstruction of habitual behaviors and the identification of causes and timing of death. We report results of an anthropological study of a case of vertebral injury discovered in an individual from the Italian Iron Age that highlights this important topic. The aim of this study was to assess the habitual activity pattern and manner of death of an ancient inhabitant of Spina in Padanian Etruria (northeastern Italy). ⋯ This Etruscan, in all likelihood a sailor according to the occupational markers, did not survive a stabbing attack with a bladed weapon.

Management of incidental asymptomatic brain tumors in children is controversial due to lack of clear evidence-based guidelines. We present this systematic review in an attempt to highlight an optimal treatment paradigm. ⋯ A small body of evidence has emerged, highlighting the marked heterogeneity and contradictory results between the available studies, limiting our ability to draw solid conclusions. At this point, the decision between surgery and "watchful waiting" should be tailored on an individual patient basis depending on suspicion of malignancy, clinical or radiologic progression, and parental preference.

Enhancing Reality: A Systematic Review of Augmented Reality in Neuronavigation and Education.
Augmented reality (AR) is increasingly being explored as an adjunct to conventional neuronavigation systems. AR affords the ability to superimpose 3-dimensional images onto the real environment. A natural extension of this technology is to help guide neurosurgical planning and a means of stereotactic planning and guidance. Here we review the literature on the use of AR in neurosurgery with a focus on current technologies and limitations. Furthermore, we discuss this technology in the context of neurosurgical training as an educational tool. ⋯ Although various AR systems have been successfully utilized across many neurosurgical disciplines, more research is needed to improve accuracy in registration and to assess whether AR-assisted surgery is safe and effective for widespread adoption.

Case Reports
Endovascular treatment of a ruptured enlarging dissecting anterior spinal artery aneurysm.
Aneurysms of the anterior spinal artery are extremely rare. Unlike intracranial saccular aneurysms, they do not occur at branch points, are typically pseudoaneurysms, and rupture secondary to a dissection. They typically present with subarachnoid hemorrhage and demonstrate clinical and radiographic improvement over time without treatment. ⋯ We analyze this case and review the literature on thoracic anterior spinal artery and artery of Adamkiewicz aneurysms.

Trans-Lamina Terminalis Approach to Laser-Assisted Resection of Thalamo-mesencephalic Cavernous Malformation.
Cavernous malformations of the midbrain require careful consideration of the risks and benefits of intervention as well as the optimal surgical approach for these challenging lesions. Excellent results can be achieved with careful surgical planning and technique. We demonstrate a contralateral left pterional craniotomy for a translamina terminalis approach to carbon dioxide laser-assisted microsurgical resection of a thalamomesencephalic cavernoma in a 59-year-old woman with progressive debilitating diplopia secondary to partial third nerve palsy (Video 1). ⋯ This approach offers a direct route to the lesion with minimal brain transgression, while avoiding the critical structures within the interpeduncular cistern, including the basilar artery and thalamomesencephalic perforating arteries, as well as bordering neural structures, including cerebral peduncles, oculomotor nerves, and mamillary bodies. Use of the carbon dioxide laser with its 0.55-mm tip offers a low surgical profile and allows for precise cutting, thus minimizing thermal damage to surrounding tissues. The translamina terminalis approach through a pterional craniotomy offers a safe and potentially less morbid alternative to select thalamomesencephalic lesions compared with exposure through the mesencephalic surface, which in our experience often necessitates an orbitozygomatic craniotomy.
