Spinal sarcoidosis is a rare subgroup of neurosarcoidosis. Although most sarcoid lesions develop in the intramedullary compartment, intradural extramedullary (IDEM) spinal sarcoidosis is an extremely rare entity. <jats:italic>Case Presentation<\/jats:italic>. We herein report a case of IDEM spinal sarcoidosis mimicking a meningioma. A 32-year-old man presented to the hospital with clumsy hands and was unable to walk without assistance. Magnetic resonance imaging (MRI) of the cervical spine revealed a dural tail sign that is common in meningiomas. The patient underwent gross total resection. The pathological findings consisted with a sarcoid leision of the spinal cord. The patient\u2019s myelopathy recovered after surgery. <jats:italic>Conclusions<\/jats:italic>. Physicians should be alert for the possibility of IDEM sarcoidosis mimicking a meningioma in the differential diagnosis of IDEM spinal cord tumors.<\/jats:p>","DOI":"10.1155\/2019\/3592980","type":"journal-article","created":{"date-parts":[[2019,8,5]],"date-time":"2019-08-05T19:30:57Z","timestamp":1565033457000},"page":"1-5","source":"Crossref","is-referenced-by-count":4,"title":["Intradural
