Owing to the rarity of acute ischemic stroke in the pediatric population, evidence supporting the efficacy in children of the various treatments used in adults is scanty. This included mechanical thrombectomy for acute ischemic stroke. ⋯ Pediatric patients likely have more reserve and collateral flow and benefit from a longer therapeutic window following acute ischemic stroke.

The inferior temporal gyrus (ITG) is known to be involved in high-cognitive functions, including visual and language comprehensions and emotion regulation. A detailed understanding of the nature of association fibers could significantly improve postoperative morbidity related to declining capacity. Through diffusion spectrum imaging-based fiber tracking, we have characterized these connections on the basis of their relationships to other cortical areas. ⋯ This study highlights the principal white-matter pathways of the ITG and demonstrates key underlying connections. We present a summary of the relevant clinical anatomy for this region of the cerebrum as part of a larger effort to understand it in its entirety.

Skull base chordomas will occasionally penetrate the clival dura mater and extend into the prepontine cistern, involving the basilar artery. Few reports have described cases of skull base chordoma accompanying a dissecting aneurysm of the basilar artery, and the treatment strategies have remained largely unknown. ⋯ We have reported a case of a dissecting aneurysm of the basilar artery with clival chordoma. Our findings suggest that chordoma with intradural vascular encasement has the potential to invade the vessel wall. To avoid rupture of those critical vascular structures, treatment strategies that minimize stress on the involved arteries and offer safe and sufficient surgical resection should be considered.

Atlantoaxial dislocation associated with type-1 neurofibromatosis: case report and review of the literature.
Neurofibromatosis type 1 (NF-1) is an autosomal dominant genetic condition in which spinal deformities are commonly involved. However, atlantoaxial dislocation in NF-1 is extremely rare. A review of the English literature has identified only 10 cases in 8 reports. We report a rare case involving NF-1 associated with severe atlantoaxial dislocation. ⋯ Atlantoaxial dislocation is a rare complication in NF-1 patients. Surgical reduction combined with fusion is essential for a good outcome. Spine surgeons should also be knowledgeable about the possibility of significant hemorrhage before surgery.

Case Reports
The Outcome of Epidural Hematoma : Lessons from Solitary Fibrous Tumor / Hemangiopericytoma-case report.
Intracranial solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) is rare. In this report, a case of epidural hematoma (EDH) that eventually evolved into SFT/HPC is presented. We describe the possible association between the 2 diseases, which has not been previously reported. ⋯ To our knowledge, this is the first report that HPC occurred in the epidural cavity. We are the first time to describe the possible association between EDH and HPC.
