• Abstract: ABSTRACT INTRODUCTION Arachnoid Web is a rare spinal cord condition characterized by the presence of an arachnoid membrane that causes spinal cord compression. Advances in imaging techniques, especially magnetic resonance imaging (MRI) and computed tomography (CT) myelography, have significantly improved diagnosis. This review addresses the definition, epidemiology, pathophysiology, differential diagnosis, and treatment options of Arachnoid Web, and discusses the importance of early diagnosis and future research perspectives. OBJECTIVES To provide a comprehensive review of Arachnoid Web, including its definition, diagnosis, pathophysiology, treatment options, and clinical outcomes. METHODS This is a narrative review. The PubMed, sciELO and Medline databases were used and the following descriptors were used: “Arachnoid Web” AND “Imaging Diagnosis” AND “Spinal Cord Compression” AND “Spinal Surgery” AND “Clinical Neurology” in recent years. RESULTS AND DISCUSSION Advances in imaging techniques, such as high-resolution MRI and CT myelography, have shown high sensitivity and specificity in identifying Arachnoid Web. The reviewed literature highlights the efficacy of surgical approaches, such as laminectomy and arachnoid web resection, in reducing symptoms and improving clinical outcomes. Neurological complications are common but can be managed with rigorous postoperative follow-up. Multidisciplinary management and early diagnosis are crucial to optimize patient outcomes. CONCLUSION Arachnoid Web is a complex condition that requires accurate diagnosis and appropriate therapeutic management. Advanced imaging techniques are essential for diagnosis, while surgical approaches such as laminectomy are effective in treatment. Future studies should focus on improving the understanding of pathophysiology and developing new diagnostic and therapeutic strategies. Multidisciplinary collaboration and continued research are vital to improve the care of patients with Arachnoid Web.
