We reported a case of arachnoid cyst in the craniovertebral junction which was extremely rare. A 36-year-old man presented truncal ataxia and dysesthesia in the right upper extremity. CT and MR images revealed a large cyst in the craniovertebral junction. As for findings of MR images, cystic lesion showed similar intensity as cerebrospinal fluid. Intradural arachnoid cyst with thickened dura was opened to communicate with subarachnoid space. Fluid in the cyst was watery clear. Histological finding of the surgical specimen was arachnoid cyst without inflammatory changes. Arachnoid cyst in the craniovertebral junction is discussed with literature.
我们报告了一例极其罕见的颅颈交界处蛛网膜囊肿病例。一名36岁男性出现躯干共济失调和右上肢感觉障碍。CT和MR图像显示颅颈交界处有一个大囊肿。就MR图像表现而言，囊性病变的信号强度与脑脊液相似。对硬膜增厚的硬膜内蛛网膜囊肿进行切开，使其与蛛网膜下腔相通。囊肿内的液体清澈如水。手术标本的组织学检查结果为无炎症改变的蛛网膜囊肿。本文结合文献对颅颈交界处蛛网膜囊肿进行了讨论。
