title: Cervical epidural lymphangioma presenting as a hemorrhagic cyst: a case report.
abstract: METHODS
  A case report.
  
  
  OBJECTIVE
  We report a case of epidural lymphangioma in the cervical spine, and it manifested as a hemorrhagic cyst.
  
  
  BACKGROUND
  Intraspinal lymphangioma is an uncommon tumor with only a few cases reported in the literature. Epidural lymphangioma presenting as a hemorrhagic cyst is extremely rare.
  
  
  METHODS
  The patient chosen was a 43-year-old woman with the chief complaint of neck pain and right upper extremity numbness of 2-month duration.
  
  
  RESULTS
  Cervical spine magnetic resonance (MR) imaging revealed an epidural cystic mass extending to the right C6-C7 neural foramen. The mass showed fluid-fluid levels on T2-weighted image and high-signal intensity on diffusion-weighted image. Surgical resection and histologic analysis confirmed the diagnosis of epidural lymphangioma with internal hemorrhage.
  
  
  CONCLUSIONS
  Epidural lymphangioma is a rare benign tumor. However, it should be included in the differential diagnosis of hemorrhagic cystic mass in the epidural space, which presented with fluid-fluid levels on MR imaging and high-signal intensity on diffusion weighted imaging.
