Lateral intraventricular anaplastic meningiomas (LIAMs) are rare lesions. The aim of this study is to clarify clinical and radiologic characteristics and the optimal treatment strategies of LIAMs with long-term follow-up. ⋯ Female and right trigone area predominance were found in our case series. Shorter duration of symptoms, irregular tumor shape, peritumoral edema, and heterogeneous enhancement may indicate an aggressive feature. Maximal safe resection followed by radiation therapy may be the best strategy for patients with LIAM. Long-term clinical follow-up and serial imaging are recommended.

Review Case Reports
Removal of migrating lumbar spine bullet: Case Report and Surgical Video.
Gunshot wounds to the spine are devastating injuries. Rarely, the bullet has been reported to migrate. Migration is associated with progressive neurologic deficits that often improve with bullet removal. The authors report a case of removal of a migrating lumbar spine bullet. This is supplemented by an operative video and a review of the literature. ⋯ Neurosurgical treatment for gunshot wounds remains controversial. Cauda equina or lumbosacral level wounds are often incomplete and may improve with surgical decompression and bullet removal. Migrating bullet fragments throughout the spine and brain lead to worsened neurologic function, which can be reversed by removal. Movement of the bullet during surgery should be expected, and intraoperative fluoroscopy and patient positioning can help to properly localize the bullet and aid in its removal.

To evaluate the surgical outcome of using a trepan to treat single-segment ossification of ligamentum flavum under endoscopy and the clinical value of the new surgical treatment. ⋯ The visual trepan technique using a spinal endoscope can be used to treat single-segment ossification of ligamentum flavum. Advantages include less trauma, faster recovery, and lower cost. However, more cases and long-term follow-up are required to further evaluate the clinical effectiveness and safety of this surgical method.

In this video, we present the case of a 61-year-old female who was brought to the emergency department after she had partial complex seizures. Computed tomography and magnetic resonance imaging of the brain revealed a right temporal lobe mass, which was initially thought to be a tumor. The patient was therefore referred to us for further management. ⋯ A strategy was then devised, which consisted of cutting the dome of the aneurysm and clearing the distal two thirds of the clot ("tulip technique") and then completing thrombus resection under temporary occlusion. Once clot removal was completed, the aneurysm was clipped using the "shingle clip cut clip" technique (Video 1). The patient's postoperative course was uneventful, and the patient remained seizure free.

To explore the performance of neurite orientation dispersion and density imaging (NODDI) in grading gliomas and to evaluate the cellular proliferation. ⋯ NODDI is a promising method in grading gliomas and predicting cellular proliferation. These results may be of great significance for the clinical diagnosis and treatment of gliomas.
