The objective of this study was to evaluate the association between asymptomatic unruptured intracranial aneurysms (IAs) and pituitary adenomas (PAs) in Chinese people. ⋯ The patients with PA have an increased incidence of IA compared with age-matched control subjects. Older age and cavernous sinus invasion might be correlated with the increased prevalence of IAs in Chinese patients with PA.

Pedicle screw instrumentation is a standard procedure in lumbar spinal fusion. The cortical bone trajectory (CBT) screw is an alternative technique, less invasive but harder to perform. The identification of the entry point and the appropriate direction can be tricky especially to the surgeons just at the beginning. Therefore, the aim of this study is to evaluate the reliability of preoperative computed tomography (CT) planning in the CBT screw placement. ⋯ The CBT screw placement is a great alternative to the pedicle screw. Accurate preoperative 3D planning is useful to predict the entry point and the direction with accuracy similar to navigation systems, avoiding its costs and technical difficulties. The 3D CT planning is helpful in the customization of spine surgery, and the results underline the radiological reliability of this technique.

Endoscopic Treatment of Thoracic Discitis with Robotic Access: A Case Report Merging Two Cutting-edge Technologies.
Emerging technologies in minimally invasive spinal surgery include surgical robots for navigation and spinal endoscopy. We applied these technologies in concert to treat a critically ill patient with thoracic discitis. ⋯ This case represents a novel endoscopic-robotic hybrid spine surgery that we believe will find further applications in spinal surgery.

Intramedullary glial neoplasms affecting the entire spinal cord from the cervicomedullary junction to conus medullaris are termed holocord tumors. Pilocytic astrocytomas are relatively uncommon tumors forming holocord involvement. Hitherto 24 holocord astrocytoma cases were reported in the literature. Here, a case of an adult holocord pilocytic astrocytoma was presented. ⋯ Reported holocord pilocytic astrocytomas in the relevant literature cases were reviewed. When evaluating magnetic resonance imaging scans of adult patients with various neurologic symptoms, i.e., weakness and fecal and urinary incontinence, pilocytic astrocytoma should be considered among differential diagnoses of intramedullary mass lesions.

Observational Study
Normal Atlanto-Occipital Interval In Adults Of South-East Nigeria: An evaluation of the effect of age, gender and race.
Imaging of the craniocervical junction (CCJ) after trauma is crucial for injury detection and description. Of all the anatomic measurements of the CCJ, the normal value of atlanto-occipital interval (AOI) is not yet well established in adults. The aim of our study is to determine the normal values of the AOI in Nigerians aged between 21 and 60 years using multidetector computed tomography (MDCT) scan and to determine racial, age, and sex differences. ⋯ AOI values in this study were higher than previous MDCT-based values in non-African populations. The AOI decreased linearly with age and did not show any sex difference.
