title: A case of intraroot cauda equina cavernous angioma: clinical considerations.
abstract: METHODS
  Case report and literature review.
  
  
  OBJECTIVE
  Intradural-extramedullary cavernoma is a rare condition with only 23 cases reported in the literature. Most cases described adhere to spinal root or spinal cord. We report an example of this rare entity located within the sheets of one cauda equina nerve root.
  
  
  METHODS
  Rome, Italy.
  
  
  METHODS
  The authors report clinical, radiological, surgical, and pathological features of intraroot cavernoma with a literature review.
  
  
  RESULTS
  Patient was operated. One year after surgery, he was healthy.
  
  
  CONCLUSIONS
  Lumbar intradural cavernous angioma may present with sciatalgia, low-back pain, neurological deficit, or, more rarely with subarachnoid hemorrhage or hydrocephalus. They are treated successfully with surgical resection but preoperative status is a predicting factor for outcome. Sometimes the sacrifice of the spinal root is inevitable because, as in present case, the cavernous angioma is included in the nerve root. These lesions are rare and benign lesions. It is important for neurosurgeons to be aware of the existence of this entity to avoid preoperative misdiagnosis with tumor.
