Comparative Study
Efficacy and safety of using high viscosity bone cement vertebroplasty in the treatment of osteoporotic vertebral compression fractures with intravertebral cleft.
To evaluate and compare clinical outcomes and cement leakage of high-viscosity bone cement versus low-viscosity bone cement vertebroplasty in treating osteoporotic vertebral compression fractures with intravertebral cleft. ⋯ Percutaneous vertebroplasty using HVC to treat osteoporotic vertebral compression fractures with intravertebral cleft significantly reduces cement leakage and improves the safety of the operation. In terms of clinical efficacy and prevention of augmented vertebral recollapse, HVC may not have obvious advantages.

Case Reports
Full-Endoscopic Lumbar Foraminoplasty for Symptomatic Cement Leakage With Exiting Nerve Root Impingement.
Foraminal stenosis, a common disorder occurring in elderly patients, is often caused by narrowing of the foramen, resulting in the confinement of neural structures by the tissue and vertebrae. Full-endoscopic lumbar foraminoplasty (FELF) is an effective treatment option for patients with foraminal stenosis. However, to the best of our knowledge, no previous study has reported the treatment of symptomatic cement leakage. We report a case of symptomatic cement leakage treated with FELF with the patient under local anesthesia. ⋯ The present report has shown that FELF can successfully remove symptomatic cement leakage, resulting in pain relief.

The rosette-forming glioneuronal tumor (RGNT) is a rare World Health Organization grade I tumor, most often originating in the fourth ventricle and characterized by a predominant glial component, as well as a neurocytic component. Despite its benign grading, there are a few documented cases of RGNT displaying more aggressive behavior with malignant characteristics. ⋯ This case supplements and complements the handful of published cases available documenting the evolution of a particularly aggressive case of disseminated RGNT.

There are no standardized criteria to predict the prognosis of patients with low-grade gliomas. Therefore, novel prognostic biomarkers that can guide follow-up schedules and therapeutic approaches urgently are required in patients with low-grade gliomas. ⋯ High preoperative NLRs were significantly associated with greater relapse and poor prognosis in patients with WHO II gliomas.

Recurrence is one of the concerns even after successful endovascular treatment of intracranial aneurysms. We sought to determine the critical aneurysm volume and risk factors related to aneurysmal stability in patients undergoing coil embolization of intracranial aneurysms. ⋯ In our series of cerebral aneurysms treated with coil embolization, 500 mm3 was found to be the critical volume determining stability after coil embolization. Large volume aneurysms in the posterior circulation were especially prone to recanalization after coiling.
