To investigate clinical features of vertebral artery (VA) occlusion and recanalization after cervical facet dislocation. ⋯ A fifth of patients with cervical facet dislocation will develop VA occlusion with rare symptomatic vertebrobasilar ischemia. VA recanalization occurs mainly within the first 4 months after injury, regardless of the length of VA occlusion.

Mixed pituitary gangliocytom and prolactinoma resistant to the cabergoline treatment: A case report.
A gangliocytoma rarely coexists with a pituitary adenoma in a sellar lesion. Herein, we describe our experience in treating a mixed gangliocytoma and prolactinoma of the pituitary gland. ⋯ Our findings showed the existence of cells that are phenotypically intermediate between ganglion cells and adenoma cells, and the existence of stem cell-like cells, which support the hypothesis that adenoma cells can transform into ganglion cells or that both ganglion and adenoma cells derive from common stem cells. Furthermore, the ganglion cells seemed to grow rapidly and independently of dopamine, which is in contrast to prototypical prolactinoma cells.

Pediatric neurosurgical cases have been identified as an important target for impacting health disparities in Uganda, with over 50% of the population being less than 15 years of age. The objective of the present study was to evaluate the effects of the Duke-Mulago collaboration on pediatric neurosurgical outcomes in Mulago National Referral Hospital. ⋯ Our data show the provision of more complex neurological procedures does not necessitate improved outcomes. Rather, combining these higher-level procedures with essential pre- and postoperative care and continued efforts in health system strengthening for pediatric neurosurgical care throughout Uganda will help to address and decrease the burden throughout the country.

Pediatric basal ganglia germ cell tumors (GCTs) represent a rare subset of tumors about which little is known. We aimed to summarize the clinical features and radiological findings of this special subgroup of GCTs. ⋯ GCTs are not as rare as considered in pediatric basal ganglia tumors. They bear some distinctive clinical and radiologic features, which can help with the accurate diagnosis and successful management of such tumors.

Case Reports
Intramedullary and extramedullary cervical neurenteric cyst requiring fixation and fusion.
Spinal neurenteric cysts are rare in the literature, described by sporadic case reports and small case series. In the vast majority of cases, these lesions are intradural extramedullary. We report the novel case of a cervical neurenteric cyst that was simultaneously intramedullary and extramedullary. ⋯ A novel case of cervical intramedullary and extramedullary neurenteric cyst is presented with clinical, radiographic, and histologic details. Given the potential for bony remodeling around these developmental tumors, the possibility exists for instability after certain neurenteric cysts are resected. Thus, the present case adds fixation and fusion to the potential treatment paradigm for select spinal neurenteric cysts.
