Presence of an arachnoid cyst at craniospinal junction is not very common. This is a very rare anatomic site, with only seven other cases reported in the literature. We report a case of large intradural craniospinal arachnoid cyst presenting with obstructive hydrocephalus and cranial nerve palsy. A 39-year-old male presented with 8-month history of neck pain, headache, vomiting, visual disturbances, diminished taste sensation, and numbness of face. He had bilateral papilledema on ophthalmoscopy. Magnetic resonance imaging (MRI) revealed a posterior fossa arachnoid cyst extending down to the lower border of C5 vertebra. Posterior decompression was done through C5 laminectomy. He made a full recovery and was asymptomatic at 6-month follow-up examination. The clinical features, diagnosis, and management of these rare craniospinal arachnoid cysts are discussed.
颅颈交界处存在蛛网膜囊肿并不常见。这是一个非常罕见的解剖部位，文献中仅报道过其他7例病例。我们报告一例巨大的硬脊膜内颅颈蛛网膜囊肿，表现为梗阻性脑积水和脑神经麻痹。一名39岁男性，有8个月的颈部疼痛、头痛、呕吐、视力障碍、味觉减退和面部麻木病史。眼科检查发现双侧视乳头水肿。磁共振成像（MRI）显示一个后颅窝蛛网膜囊肿向下延伸至C5椎体下缘。通过C5椎板切除术进行后路减压。患者完全康复，在6个月的随访检查中无症状。本文讨论了这些罕见的颅颈蛛网膜囊肿的临床特征、诊断和治疗。
