Leptomeningeal carcinomatosis following neoplastic cerebral aneurysm rupture: a case report.
Several possible mechanisms exist for the spread of a primary tumor to the leptomeninges in leptomeningeal carcinomatosis. This report describes a case caused by direct bleeding in the subarachnoid space from a neoplastic cerebral aneurysm rupture. ⋯ Tumor cells reach the leptomeninges via hematogenous spread or direct extension from preexisting lesions and can undergo neuraxis dissemination via the cerebrospinal fluid. Subarachnoid hemorrhage and leptomeningeal carcinomatosis are both devastating conditions with extremely poor prognoses. This patient experienced delayed disturbed consciousness leptomeningeal carcinomatosis with decreased performance status, which made it difficult to justify aggressive treatment on the basis of her poor prognosis.

Medical publications reflect the development of training, research, and health services. No objective data are available regarding neurosurgical publications from Morocco. Bibliometrics were used to evaluate the contribution of Moroccan neurosurgeons (MONSs) in neurosurgical journals worldwide and to discuss the strategies that can be applied to increase the quantity and quality of publications on this subject. ⋯ Academic neurosurgeons in Morocco should prepare their residents and young researchers on research methodology and medical writing. Moroccan neurosurgical research should be more focused on modern neurosurgical topics by highlighting our particularities. More high level of evidence studies should be reported in English-language neurosurgical journals with a high impact factor and good scientific reputation. MONSs should continue to collaborate more often with each other and with foreign centers to further improve the quality and number of international publications, regardless of the difficulties they face.

Long-term data about the incidence of late adverse radiation effects (AREs) in pediatric brain arteriovenous malformations (AVMs) treated with Gamma Knife radiosurgery (GKRS) are lacking. This study addresses the incidence of late AREs, including cyst formation (CF), chronic encapsulated hematoma (CEH), and radiation-induced tumor, in pediatric patients with AVM treated with GKRS. ⋯ GKRS is a reasonable treatment option for pediatric AVMs to prevent future intracranial hemorrhages, particularly in the eloquent regions. However, considerable attention should be paid to late AREs such as CFs, CEHs, and radiation-induced tumors because of longer life expectancy in pediatric patients.

Use of Pterional Craniotomy for Removal of Penetrating Object: Video Submission and Case Report.
Penetrating injuries are dangerous because they can damage intracranial structures. Removal of the object carries this same risk of injury, so neurosurgeons often visualize the injury via craniotomy during removal. ⋯ The patient progressed well without complications postoperatively and was discharged 5 days later. We provide a report with video showing our surgical approach for removal of a penetrating object through the tuberculum sellae.

Endoscopic partial facetectomy (EPF) is an effective option for decompressing the lumbar exiting root without causing spinal instabilities in the treatment of patients with degenerative lumbar foraminal stenosis. The aim of the present study was to identify the preoperative risk factors of poor clinical outcomes after EPF in patients with degenerative lumbar foraminal stenosis. ⋯ A morphological change in vertical collapse found on preoperative magnetic resonance imaging and decreased LL were significant predictors of poor clinical outcomes after EPF in the treatment of lumbar foraminal stenosis.
