We introduce a technique that uses intraoperative flat-panel detector computed tomography (FD-CT) and three-dimensional rotational angiography (3D-RA) acquired in the hybrid operative suite to provide full neuronavigation capabilities during cerebrovascular surgery without the use of preoperative imaging studies. ⋯ Hybrid operating suites equipped with FD-CT, 3D-RA, and NNS capabilities can be used to provide intraoperative 3D image guidance during cerebrovascular surgery with excellent accuracy and without the need for preoperative angiography. Furthermore, this technique required less than 15 minutes for image acquisition and utilizes digitally subtracted angiographic images that are superior to conventional CT or MRI for the imaging of cerebrovascular pathology.

Accurate image guidance is an essential component of percutaneous procedures in the head and neck. The combination of preprocedural magnetic resonance imaging (MRI) with cone-beam computed tomography (CBCT) and real-time fluoroscopy (the "triple-overlay" technique) could be useful in image-guided targeting of lesions in the head and neck. ⋯ The combination of MRI, CBCT, and real-time fluoroscopy provides detailed anatomical information for 3D image-guided percutaneous procedures of the head and neck, especially for small lesions or lesions with features visible only by MRI.

This study sought to describe a patient with a slowly progressive cauda equina syndrome (CES) who had imaging findings of the CES that occurs as a rare complication of ankylosing spondylitis (AS), but whose spinal fusion was due to thoracolumbosacral instrumentation, not spondyloarthropathy. ⋯ This case strongly suggests that extensive surgical thoracolumbosacral fusion can, rarely and after many years, be associated with lumbosacral nerve root damage and a slowly progressive CES that is similar to that seen in patients with spinal fusion due to longstanding AS.

Gross total resection correlates with long-term survival in pediatric patients with glioblastoma.
Glioblastoma is a rare central nervous system neoplasm in pediatric patients. Few studies focused exclusively on this disease in this population. Available literature suggests that this disease behaves differently between pediatric and adult patients. We set out to study patients younger than 18 years of age, carrying the diagnosis of glioblastoma not of the brainstem, their clinical characteristics and clinical factors associated with clinical outcome. ⋯ GTR significantly associates with long-term survival in our population of pediatric patients with glioblastoma not of the brainstem.

Seizures are common among patients with meningiomas and are a significant cause of morbidity and poor quality of life. The factors associated with the onset of seizures as well as factors associated with seizure control remains poorly understood. ⋯ With the widespread availability of various neuroimaging modalities, there will be increased detection of intracranial meningiomas. The identification and consideration of factors associated with seizure onset and prolonged seizure control may help guide treatment strategies aimed at improving the quality of life for patients with meningiomas.
