Intracranial Castleman's Disease Mimicking Dural-based Pathologies: A Case Report.

Background: Castleman disease (CD) is a rare lymphoproliferative disorder, with intracranial involvement being exceedingly rare. Unicentric Castleman disease (UCD) is typically benign and localized, but its presentation can mimic other intracranial pathologies, complicating diagnosis.

Case Description: We reported a 52-year-old woman who presented with progressive headaches and language disturbances.

True Posterior Communicating Artery Aneurysm Associated With a Posterior Communicating Segment Aneurysm: A Case Report.

"True" posterior communicating artery (PComA) aneurysms are one of the rarest of all intracranial aneurysms. Diagnosis of this kind of aneurysm and treatment continue to be challenging for neurosurgeons because of the surrounding structures and their importance. Concomitant vascular anomalies, like dissections or hypoplasia, are frequently found with these aneurysms.

Bone anatomic variations of the parasellar region and its technical implications in para clinoid and posterior communicating segment aneurysms microsurgical clipping - Technical note.

Background: Microsurgical treatment of paraclinoid aneurysms is a complex task that generally requires anterior clinoid process (ACP) removal to obtain adequate surgical exposure. This procedure poses a considerable technical difficulty due to the association of the ACP to critical neurovascular structures. Furthermore, anatomical variations in the parasellar region, such as the caroticoclinoid foramen (CCF) or an interclinoid bridge (ICB), may impose additional challenges and increase surgical complications.

Necrotizing Parasagittal Meningioma in Patient with Systemic Lupus Erythematosus after Treatments with Methotrexate and Hydroxychloroquine.

 Meningiomas are the most common extra-axial tumors of the central nervous system. Meningiomas are particularly problematic when they invade deep or vital structures, causing the tumors to be inoperable. Nonsurgical adjunctive or salvage treatments to shrink a meningioma with multiple recurrences, located in deep-seated area or surgically unfit area, remain underexplored.

Feasibility of Endoscopic Lumbar Discectomy in a Remote Government Hospital in Thailand: A Cost-Utility Analysis.

Background: Treatments for lumbar discectomy have developed over time. Recently, endoscopy has played an important role. However, a major obstacle to endoscopy in rural areas is the cost of surgery, particularly for endoscopes and disposable equipment.

Atlas of Nervous System Vascular Malformations: A Systematic Review.

Vascular malformations are frequent in the head and neck region, affecting the nervous system. The wide range of therapeutic approaches demand the correct anatomical, morphological, and functional characterization of these lesions supported by imaging. Using a systematic search protocol in PubMed, Google Scholar, Ebsco, Redalyc, and SciELO, the authors extracted clinical studies, review articles, book chapters, and case reports that provided information about vascular cerebral malformations, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.
