The C1-C2 joint has multiple degrees of freedom of movement and C1-C2 dislocation (AAD) is often multiplanar. The existing methodology to assess the dislocation is limited to few planes. The object of this study is to redefine and objectively assess congenital AAD in each possible plane, before and after the operation. ⋯ The objective assessment of C1-C2 dislocation and joints in each plane was to determine its management and help in achieving multiplanar correction.

To study the curative effect and prognosis of patients with basal ganglia cerebral hemorrhages treated using a transcortical-sulcus approach and compare with results obtained using the traditional cerebral cortex approach. ⋯ The transcortical-sulcus approach can significantly improve the prognosis of patients with intracerebral hemorrhages in the basal ganglia and reduce the incidence of postoperative seizures.

Hemiballismus is a rare presentation of symptomatic carotid stenosis that is underreported in the neurosurgical literature. It is characterized by severe large-amplitude movements that are classically caused by lesions of the subthalamic nucleus. Given the arterial border zone position of the subthalamic nucleus between the anterior and posterior circulation, hemodynamically compromising carotid stenosis can lead to hypoperfusion in this location. ⋯ We suggest that neurovascular imaging should be part of the initial workup of this condition and that prompt diagnosis and treatment of carotid artery stenosis in patients who present with new-onset hemiballismus are essential for reducing risk of imminent stroke.

Glioblastoma can mimic various pathologies, including arteriovenous malformation, hemorrhage from ischemic stroke, cerebral contusion, metastatic disease, lymphoma, and infection. The literature is limited regarding diagnostic confusion with meningioma. Herein, we present 2 patients that exhibited imaging, including cerebral angiography during preoperative embolization, which was consistent with meningioma, but where final surgical diagnosis revealed glioblastoma. ⋯ Glioblastoma can mimic meningioma on MRI with dural tail sign, CSF cleft sign, and broad dural contact. Moreover, cerebral angiography can reveal tumor feeders commonly associated with meningioma. These features can contribute to diagnostic confusion. Based on these 2 cases, preoperative embolization of tumor feeders is possible with glioblastoma.

To evaluate spinal implant density and proximal junctional kyphosis (PJK) in adult spinal deformity (ASD). ⋯ PJK, although influenced by a multitude of factors, may be statistically related to implant density and LL.
