Intradural spinal varices are rare lesions, with only three cases being previously reported in the literature. Previously described patients underwent MRI for non-specific low back pain and radiculopathy and were found to have an intradural lesion adjacent to the cauda equina, mimicking a nerve sheath tumour or ependymoma. Consideration of an intradural varix in the differential diagnosis of an intradural extramedullary spinal lesion is necessary to guide appropriate management. We report a case of an intradural spinal varix diagnosed with first-pass arterial and blood pool phase gadolinium-enhanced auto-triggered elliptic centric-ordered MR angiography. Digital subtraction angiography confirmed that there was no shunt but failed to demonstrate the varix. We reviewed the existing literature to look for common clinical and imaging features.

Spinal Dumbbell Meningiomas: A Systematic Review.
Ann Ital Chir
December 2024
Neurosurgery Unit, Department of Head and Neck Surgery, Garibaldi Hospital, 95124 Catania, Italy.
Aim: This systematic review aims to synthesize the epidemiology, clinical presentation, diagnostic approaches, treatment strategies, and outcomes of spinal dumbbell meningiomas to enhance understanding and improve patient management.
Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, four major databases (PubMed, Scopus, Web of Science, and Cochrane Library) were searched until June 2024. Studies included patients diagnosed with spinal dumbbell intradural-extradural meningiomas, focusing on patient demographics, tumor characteristics, diagnostic methods, treatment modalities, and clinical outcomes.
Concordance of Extent of Resection Between Intraoperative Ultrasound and Postoperative MRI in Brain and Spine Tumor Resection.
Cureus
November 2024
Neurosurgery, Tecnologico de Monterrey, Monterrey, MEX.
Objective Evaluate the utility of intraoperative ultrasound (IOUS) in brain and spinal tumor resections and the concordance of the extent of resection between IOUS and postoperative magnetic resonance imaging (MRI). Methods A retrospective analysis of prospectively collected data was performed. Thirty-nine lesions (36 patients) in the brain and spine were operated on for resection using IOUS between May 2020 and December 2022.

Introduction: Spinal schwannomas are benign intradural extramedullary tumors of Schwann cells, while hemangiomas are common benign vascular tumors found in the vertebral column.
Case Representation: This case study presents a 32-year-old male who developed both a spinal schwannoma and multiple thoracic vertebral haemangiomas following a COVID-19 infection and subsequent vaccination. The patient reported intermittent lumbar and thigh pain over 6-8 months.
Schwannomas of C1: A Novel Classification and Description of Growth Patterns Based on a Personal Series and Review of Literature.

November 2024
Department of Neurosurgery, Kauvery Institute of Brain and Spine, Kauvery Hospital, Chennai, Tamil Nadu, India.
Background: Schwannomas of C1 are rare tumors. Because of the wide variation in their anatomy, and presentation and their rarity, there is no proper understanding of their pathological anatomy nor their optimal management.
Methods: A retrospective study of the C1 schwannomas operated by the author between 2000 and 2020 and a PubMed-based search of English literature were done to analyze data on the location and extent of the lesions, surgical approaches used, and operative outcomes.

This systematic review consolidates the literature on primary extradural meningiomas (PEMs), a rare subset of meningiomas. We describe the clinical features, management strategies used, and treatment outcomes for published cases. A systematic review was conducted using PRISMA guidelines across multiple databases to 29 July 2024.
