A 48-yr old man noted gradual onset of pain, and paresthesia on the lateral aspect of his right leg. The findings were suggestive of S1 root compression. CT of spine was normal. Physical examination revealed a small mass overlying the right fibular head. CT revealed this to be a cystic mass. At surgery a ganglion cyst compressing the common peroneal nerve was found. Peripheral nerves may be compressed by ganglia producing a syndrome mimicking central nerve root compression. CT is the modality of choice for detection of these lesions.
一名48岁男性注意到其右腿外侧逐渐出现疼痛和感觉异常。这些表现提示S1神经根受压。脊柱CT检查结果正常。体格检查发现右腓骨头上方有一个小肿块。CT显示这是一个囊性肿块。手术中发现一个压迫腓总神经的腱鞘囊肿。腱鞘囊肿可能压迫周围神经，产生一种类似中枢神经根受压的综合征。CT是检测这些病变的首选检查方法。
