title: Spinal angiolipoma: etiology, imaging findings, classification, treatment, and prognosis.
abstract: OBJECTIVE
  To summarise our experience treating patients with spinal angiolipomas (SAs) and to evaluate factors relating to its prognosis.
  
  
  METHODS
  We retrospectively reviewed the records of patients diagnosed with SAs who received surgical treatment from January 2001 to February 2013.
  
  
  RESULTS
  Twenty-one patients were described. We divide SAs into two types: "intraspinal" and "dumbbell-shaped". The former were further subclassified as "with lipomatosis" and "without lipomatosis". Overweight people are more likely to get the "with lipomatosis" type which needs different surgical strategy and/or a diet therapy to get better outcomes.
  
  
  CONCLUSIONS
  Diagnosis of SAs should be made with reference to clinical, radiological, and pathological findings. Application of different methods is needed to treat SAs.
