title: Intramedullary spinal sarcoidosis masquerading as cervical stenosis.
abstract: OBJECTIVE
  Intramedullary spinal sarcoidosis is a difficult diagnosis to make because of its nonspecific clinical and imaging features and its imitation of other common spine disorders. We present a patient with intramedullary spinal sarcoidosis that mimicked spinal cord injury from a cervical disk herniation.
  
  
  METHODS
  Relevant information was extracted from the patient's medical and imaging records. A thorough literature review subsequently was performed.
  
  
  RESULTS
  A 59-year-old woman presented to our institution with several months of intermittent parathesias, pain, and subjective weakness in her right upper and lower extremities. Magnetic resonance imaging of the cervical spine demonstrated a large osteophyte-disk complex at C4-5 adjacent to a small area of intramedullary spinal cord enhancement. The patient underwent C4-5 anterior cervical diskectomy and fusion for the osteophyte-disk complex. She initially improved postoperatively but subsequently worsened after a few months. Because of more prominent spinal cord enhancement, a posterior laminectomy and biopsy of the enhancing lesion was performed. Intramedullary spinal sarcoidosis was diagnosed, and she was treated medically with steroids and immunosuppressive agents.
  
  
  CONCLUSIONS
  Spinal sarcoidosis can mimic more common disease processes, such as cervical spondylosis. It is an important consideration in the diagnosis of intramedullary or intradural lesions of the spinal cord because early medical treatment may improve the course of the disease process. Surgery should be limited to biopsy for diagnostic purposes.
