Diagnosis and surgical treatment strategies for spinal extradural arachnoid cyst: Case report and treatment insights

Le résumé fourni par la source

INTRODUCTION: Spinal extradural arachnoid cyst (SEAC) is a rare condition that can cause significant neurological symptoms. Accurate diagnosis and effective surgical treatment are crucial for patient recovery. This study aims to elucidate the diagnostic process and surgical treatment strategies for SEAC through a case report. CASE PRESENTATION: A 33-year-old female patient with no significant medical history presented with intermittent lower back pain for over three months, which gradually worsened, but without accompanying limb numbness or weakness. Neurological examination revealed no abnormalities. Magnetic resonance imaging (MRI) and myelography confirmed a spinal extradural arachnoid cyst at the thoracic level. The patient underwent minimally invasive surgical resection of the cyst and dural repair, resulting in significant relief of pain postoperatively. DISCUSSION: This case highlights the importance of precise diagnostic localization and meticulous surgical technique in treating SEAC. The patient showed significant improvement in symptoms post-surgery, with no recurrence observed during follow-up. CONCLUSION: The successful treatment of SEAC in this case demonstrates the effectiveness of minimally invasive surgical resection and dural repair. This case provides valuable insights and recommendations for managing similar cases in clinical practice.
