Optical neuronavigation without rigid pin fixation of the head may lead to inaccurate results because of the patient's movements during awake surgery. In this study, we report our results using a skull-mounted reference array for optical tracking in patients undergoing awake craniotomy for eloquent gliomas. ⋯ A skull-mounted reference array is a simple and safe method for optical neuronavigation tracking without rigid pin fixation of the patient's head.

Brain surgery to promote behavioral or affective changes in humans remains one of the most controversial topics at the interface of medicine, psychiatry, neuroscience, and bioethics. Rapid expansion of neuropsychiatric deep brain stimulation has recently revived the field and careful appraisal of its 2 sides is warranted: namely, the promise to help severely devastated patients on the one hand and the dangers of premature application without appropriate justification on the other. ⋯ This goal is accomplished by a detailed reassessment of numerous case reports and small-scale open or controlled trials in their historical and social context. The different surgical approaches, their rationale, and their scientific merit are discussed in a manner comprehensible to readers lacking extensive knowledge of neurosurgery or psychiatry, yet with sufficient documentation to provide a useful resource for practitioners in the field and those wishing to pursue the topic further.

Comparative Study
Healthcare costs of spontaneous aneurysmal subarachnoid hemorrhage for rehabilitation, home care and in-hospital treatment for the first year.
Given the young age of onset and high probability of long-term disability after subarachnoid hemorrhage (SAH), the financial impact is expected to be substantial. Our primary objective was to highlight subsequent treatment costs after the acute in-hospital stay, including rehabilitation and home care, compared with costs for ischemic stroke. ⋯ Aneurysmal SAH prevalently affects working individuals with long-term occupational disability necessitating long-term medical rehabilitation for most patients and subsequent nursing care in one third of survivors. Overall, SAH treatment generates far higher costs than reported for ischemic stroke.

Radiation-induced meningioma (RIM) is an uncommon late risk of cranial irradiation. We conducted an exhaustive review of individual patient data to characterize RIM. ⋯ For patients treated with cranial radiotherapy, the risk of secondary meningioma warrants a longer follow-up period beyond the standard time frame typically designated for determining the risk of primary tumor relapse.

Intracranial infectious aneurysms (IIAs) are a rare but unique subtype of potentially life-threatening vascular lesion. However, there is no widely accepted standard protocol for their management. We reviewed our treatment experiences of IIAs from 2001 to 2015 and proposed a treatment strategy for future use. ⋯ All patients with IIAs should undergo appropriate antibiotic therapy. In cases with unruptured IIA, patients can be managed using medical therapy with antibiotics alone for 4-6 weeks. However, neurosurgical treatment should be considered in cases of ruptured IIA or unruptured IIA that do not respond to antibiotic therapy.
