Few meningiomas of the lumbar spine have been presented. Extracranial metastasis of meningioma occurs extremely rare, only in about 0.1% of meningiomas. Even metastasis, the sites are seldom seen in deep soft tissue. We reported a woman original meningioma in the lumbar spine with distal deep neck metastasis. Findings: A 59-year-old patient suffered from severe right drop foot, numbness, and radicular pain for the previous 6 months. Computed tomography (CT) disclosed a huge, macrolobulated retroperitoneal soft-tissue lesion with a size of 14.9 × 10.8 × 17.7 cm. Magnetic resonance imaging (MRI) further revealed a solid spinal intracanal tumor with moderate enhancement involving the right paraspinal region at the L2∼L5 level and the right iliac fossa. A meningioma was diagnosed with histological proof. Four months later, another metastatic meningioma in her left neck. She was managed conservatively without neurologic dysfunction. Conclusions: To the best of our knowledge, such a large meningioma of the lumbar spine has not previously been reported in the literature. In this study, we demonstrated a rare spinal meningioma located in the lumbar spine primarily with secondary soft tissue metastasis.enLumbar spine; Meningioma; Metastatic; Neck metastasis; Spinal meningioma[SDGs]SDG3journal article10.1080/10790268.2018.1564993306241572-s2.0-85059898289https://api.elsevier.com/content/abstract/scopus_id/85059898289
