The pyriformis syndrome is a rare entrapment neuropathy in which the sciatic nerve is compromised by the pyriformis muscle or other local structures. It usually presents with sciatic pain and hypoaesthesia and a limp caused by weakness of the gluteus maximus muscle. Peroneal nerve innervated muscles and hamstrings are also usually affected. The diagnosis relies on the clinical presentation and the EMG findings. Other causes of symptoms should be excluded by careful examination, detailed x-ray studies of the lumbosacral spine (including myelogram), sacro-iliac and hip joints. A case of this syndrome occurring in a previously healthy 42 year old woman and her follow-up investigations are reported.
梨状肌综合征是一种罕见的卡压性神经病变，其中坐骨神经受到梨状肌或其他局部结构的压迫。它通常表现为坐骨神经痛、感觉减退以及因臀大肌无力导致的跛行。腓总神经支配的肌肉和腘绳肌通常也会受到影响。诊断依赖于临床表现和肌电图检查结果。应通过仔细检查、腰骶椎的详细X线研究（包括脊髓造影）、骶髂关节和髋关节检查排除其他症状原因。本文报道了一例发生在一名42岁既往健康女性身上的该综合征病例及其后续检查情况。
