Piriformis syndrome (PS) is an unusual cause of sciatica that, because of the lack of strict diagnostic criteria, remains a controversial clinical entity. The diagnosis of PS is still primarily clinical because no diagnostic tests have proven to be definitive. We report the case of a 30-year-old woman, affected by a severe scoliosis, who developed a persistent buttock pain resembling that of PS. The clinical suspicion was confirmed by magnetic resonance imaging (MRI) of the pelvis, which showed an enlargement of the left piriformis muscle with an anterior isplacement of the sciatic nerve. The role of MRI in the diagnosis, clinical definition, and therapeutic approach to PS is discussed.
梨状肌综合征（PS）是坐骨神经痛的一种不常见病因，由于缺乏严格的诊断标准，它仍是一个存在争议的临床实体。PS的诊断目前仍主要依靠临床判断，因为尚无诊断性检查被证实具有决定性意义。我们报告了一例30岁患有严重脊柱侧弯的女性病例，她出现了类似PS的持续性臀部疼痛。骨盆的磁共振成像（MRI）证实了临床怀疑，该检查显示左侧梨状肌增大且坐骨神经向前移位。本文讨论了MRI在PS诊断、临床定义及治疗方法中的作用。
