The authors report a case of cauda equina compression by intradural hydatid cyst. An 18-year-old man presented with paraparesis and sphincter dysfunction. MRI showed an intradural cystic lesion extending from L1 to L2 with low signal intensity on T1 and high signal intensity on T2. The cyst was removed after laminectomy and opening of the dural sac. Histological and parasitic examinations confirmed a diagnosis of hydatid cyst. The patient improved progressively after surgery. The similar 22 cases of intradural extramedullary hydatid disease reported in the literature were reviewed. All spinal areas were involved, with a predilection for the thoracic region. Neurological complications were usual with rapid spinal cord compression in this rare form of hydatid disease. The treatment was by surgery with a favourable outcome compared to the classic hydatid cyst of the spine.
作者报告了一例硬膜内包虫囊肿压迫马尾神经的病例。一名18岁男性出现双下肢轻瘫和括约肌功能障碍。磁共振成像（MRI）显示一个硬膜内囊性病变，从L1延伸至L2，T1加权像呈低信号强度，T2加权像呈高信号强度。经椎板切除术和打开硬膜囊后，囊肿被切除。组织学和寄生虫学检查确诊为包虫囊肿。患者术后逐渐好转。对文献中报道的类似22例硬膜内髓外包虫病病例进行了回顾。所有脊髓区域均受累，以胸段最为常见。在这种罕见的包虫病形式中，神经并发症常见，且脊髓受压迅速。与经典的脊柱包虫囊肿相比，手术治疗效果良好。
