We report a case of a 47-year-old woman with a posterior fossa cyst associated with syringomyelia and hydrocephalus. Her birth was traumatic and she had suffered a fractured skull. About 10 years prior to coming to our department she had occipitalgia and a pain had developed over a month from her right shoulder to hand. Shortly before presenting occasional electric-like shocks were felt in her right hand associated with coughing and hiccuping. Magnetic resonance imaging (MRI) revealed a large midline posterior fossa cyst, hydrocephalus and syrinx (C1-Th11). Cisternography could not demonstrate communication between the cyst and the subarachnoid space and the 4th ventricle was present but without communication with the cyst. The cyst was tentatively diagnosed as an arachnoid cyst. One week after placement of a cyst-peritoneal shunt, CT scans showed a decrease in cyst and ventricle size and 2 months later a follow-up MRI revealed resolution of the syringomyelia. We suspected that cyst-peritoneal shunt was effective for this patient who had syringomyelia associated with incommunicated posterior fossa cyst.
我们报告一例47岁女性，患有与脊髓空洞症和脑积水相关的后颅窝囊肿。她出生时难产，曾有颅骨骨折。在来我院就诊前约10年，她出现枕部疼痛，并在一个月内从右肩至手部逐渐出现疼痛。在就诊前不久，她感到右手偶尔出现类似电击样的刺痛，与咳嗽和打嗝有关。磁共振成像（MRI）显示一个巨大的中线后颅窝囊肿、脑积水和脊髓空洞（C1-Th11）。脑池造影未能显示囊肿与蛛网膜下腔之间的交通，第四脑室存在但与囊肿无交通。该囊肿初步诊断为蛛网膜囊肿。囊肿-腹腔分流术后一周，CT扫描显示囊肿和脑室大小减小，2个月后随访MRI显示脊髓空洞症消失。我们怀疑囊肿-腹腔分流术对该患有与非交通性后颅窝囊肿相关的脊髓空洞症的患者有效。
