We report an uncommon case of a 76-year-old woman who presented with lower back pain, an intermittent L5 radiculopathy and a right palpable paraspinal mass. Imaging studies revealed a 7-cm lumbar paraspinal pseudo-cystic soft tissue tumour developed in the paravertebral musculature, without a clear radiological diagnosis. Gross total surgical resection was performed, resulting in complete resolution of pain. Histopathological studies revealed an intramuscular (IM) myxoma. With a low positive predictive value of radiological work-up and a poor yield of percutaneous biopsies, surgery remains the mainstay treatment for these rare soft tissue tumours of the lumbar spine. Intramuscular myxomas show excellent postoperative results.
我们报告了一例罕见病例，一名 76 岁女性因腰痛、间歇性 L5 神经根病和右侧可触及的脊柱旁肿块就诊。影像学研究显示，在椎旁肌肉中出现了一个 7 厘米的腰椎脊柱旁假性囊肿性软组织肿瘤，但没有明确的影像学诊断。进行了完全的大体肿瘤全切除，疼痛完全缓解。组织病理学研究显示为肌内（IM）黏液瘤。由于影像学检查的阳性预测值较低，经皮活检的检出率也较低，手术仍然是这些罕见的腰椎软组织肿瘤的主要治疗方法。肌内黏液瘤的术后效果极佳。
