Sciatica can occur due to a spinal lesion, intrapelvic tumor, diabetic neuropathy, and rarely piriformis syndrome. The causes of piriformis syndrome vary by a space-occupying lesion. A ganglionic cyst can occur in various lesions in the body but seldom around the hip joint. In addition, sciatica due to a ganglionic cyst around the hip joint has been reported in one patient in Korea who underwent surgical treatment. We experienced two cases of sciatica from a piriformis ganglionic cyst and we report the clinical characterics and progress after non-operative treatment by ultrasonography-guided aspiration. The two cases were diagnosed by magnetic resonance imaging and were treated by ultrasonography-guided aspiration. We followed the patients for more than 6months. The symptoms of piriformis syndrome from the ganglion improved following aspiration and this conservative treatment is a treatment method that can be used without extensive incision or cyst excision.
Level IV historical case.
坐骨神经痛可由脊柱病变、盆腔肿瘤、糖尿病性神经病引起，很少由梨状肌综合征引起。梨状肌综合征的病因因占位性病变而异。神经节囊肿可发生在身体的各种病变中，但很少发生在髋关节周围。此外，韩国曾有一例髋关节周围神经节囊肿引起的坐骨神经痛患者接受了手术治疗。我们遇到了两例由梨状肌神经节囊肿引起的坐骨神经痛病例，并报告了超声引导抽吸后的非手术治疗的临床特征和进展。这两例病例均经磁共振成像诊断，并采用超声引导抽吸治疗。我们对患者进行了超过 6 个月的随访。抽吸后，梨状肌综合征的症状从神经节改善，这种保守治疗是一种无需广泛切开或囊肿切除即可使用的治疗方法。
