title: [Embolisation of aneurysmal bone cysts as a minimally invasive treatment option - presentation of two cases].
abstract: OBJECTIVE
  The aim of this study was to evaluate embolisation as a therapy option for aneurysmal bone cysts of the trunk.
  
  
  METHODS
  Case reports about two males with intermittent pseudo-radicular lumboischialgia and coxalgia are discussed.
  
  
  RESULTS
  The diagnostic work-up and biopsies verified an aneurysmal bone cyst in both males. In one patient the tumour-like lesion was localised in the fifth lumbar vertebral body, in the other in the left ischium and pubis. Arterial embolisation was performed in both cases. Follow-up at 6 and 24 months after embolisation showed a significant increase of sclerosis and a reduced volume of the cysts.
  
  
  CONCLUSIONS
  In accord with literature data, arterial embolisation seems to be a sufficient and minimally invasive therapy option in aneurysmal bone cysts of the spine and the pubis.
