Atypical sciatic pain without apparent discogenic origin should raise the possibility of a non-discogenic etiology, especially tumoral but also infectious or inflammatory. We report the case of a young patient presenting with non-discogenic S1 radiculopathy due to sciatic nerve involvement in the subpiriformis canal secondary to piriformis muscle inflammation. The authors review technical considerations and results of MRI which is of great value in the evaluation of piriformis muscle pathology.
无明显椎间盘源性病因的非典型坐骨神经痛应提高非椎间盘源性病因的可能性，特别是肿瘤性病因，但也包括感染性或炎性病因。我们报告了一例年轻患者，因梨状肌炎症继发坐骨神经在梨状肌下管受累，出现非椎间盘源性S1神经根病。作者回顾了MRI的技术要点及结果，MRI在评估梨状肌病变方面具有重要价值。
