椎管内肠源性囊肿的诊断与显微外科治疗

The diagnosis and microsurgical treatment of intraspinal enterogenous cyst

目的总结椎管内肠源性囊肿的诊断及治疗的经验。方法回顾性分析11例椎管内肠源性囊肿的临床表现、MRI特点和手术结果。结果11例均有不同程度的肢体活动障碍，部分伴有脊柱发育畸形，主要的临床表现为神经根性痛和脊髓压迫症状。MRI可清晰显示囊肿及其周围结构。囊肿通常表现为稍长T1、长他均匀信号。11例中4例全切，7例大部切除。所有病例术后神经功能恢复良好。结论肠源性囊肿是少见的先天性疾患，多发生于颈胸段椎管硬膜下脊髓腹侧，常伴有脊椎畸形。MRI是最方便有效的检查方法。手术切除囊肿，神经功能多能恢复。

Objective To summarize the experience of the diagnosis and treatment of intraspinal enterogenous cyst. Methods The clinical manifestations , MRI characteristics and surgical results of 11 cases of intraspinal enterogenous cysts were analyzed. Results The main symptoms were radical pain and spine cord compression. MRI could clearly demonstrate the exact extension of the cyst and the surrounding structures. These cysts showed as slightly long T1 and long T2 homogeneous signal on MRI. Their neurological functions were improved steadily after complete resection in 4 cases, subtotal resection in 7 cases. Conclusions Intraspinal enterogenous cyst is a rare congenital lesion, often associated with vertebral anomalies and occurred at subdural cervical - thoracic location , anterior to spinal cord. MRI is an effective and convenient method for intraspinal enterogenous cyst image investigation. Total or subtotal resection of cyst with subsequent recovery in neurological function is usually possible.
