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.

We aimed to describe our single-center experience in treating cerebellar arteriovenous malformations (AVMs) with microsurgical resection. ⋯ Good outcome can be achieved by microsurgical resection in most patients with cerebellar AVMs. Increasing age at surgery, poor presurgical functional status, eloquent AVM location, and presurgical rehemorrhage are independent predictors of poor outcomes after AVM resection. We recommend early surgical resection for all surgically accessible cerebellar AVMs to prevent subsequent hemorrhage and resultant poor neurologic outcomes.

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.

To develop modified finite element models to simulate degenerative lumbar scoliosis (DLS) based on the normal lumbar spine model and to investigate the facet joint force of the DLS. ⋯ With the asymmetric loading, facet joints compressive deformation appears on the concave side, and it decreases in the effect of the facet joints to limit the vertebral rotation and listhesis. Asymmetric loading on facet joint contact forces accelerates asymmetry in the lumbar spine.

The correct timing and technique of neural tube defect (NTD) repairs significantly decrease the morbidity and mortality of NTD cases. However, infections related to the surgery are still common. We investigated the effects of topical rifampin combined with routine prophylaxis in newborns with open NTDs. ⋯ The use of topical rifampin is an easy and effective method for reducing SSIs and meningitis/VP shunt infections related to NTD surgery.
